    Full Text Available Se realizó una investigación descriptiva y transversal en 57 pacientes con fracturas faciales adquiridas durante la actividad deportiva, los cuales fueron atendidos en el Servicio de Cirugía Maxilofacial del Hospital Provincial "Saturnino Lora" de Santiago de Cuba, en el quinquenio 1992-1996. Este tipo de lesión representó el 6,2 % del total de tratadas en dicho período. En los atletas que jugaban con pelota y practicaban técnicas de combate hubo la mayor prevalencia de estas lesiones, fundamentalmente en los deportes de pelota, boxeo, baloncesto, karate y softbol. El impacto contra otro atleta fue el mecanismo de lesión más frecuente, sobre todo en los grupos de combate y juegos con pelota. Las fracturas de mandíbula dentoalveolares y cigomáticas resultaron ser los patrones de fracturas preponderantes. La conducta terapéutica en estos pacientes no difirió sustancialmente de la aplicada en aquellos con lesiones producidas por otras causas. La restricción de la actividad atlética osciló entre 9 y 15 semanas después del tratamiento inicial. En los atletas de alto rendimiento lesionados se impone establecer las estandarizaciones en su proceso rehabilitador para la toma de decisiones con respecto a su incorporación, tanto a la práctica como a la competencia, lo cual es fundamental en este sentido.A descriptive cross-sectional research study was made on 57 patients with facial fractures suffered during sporting activities. These patients had been seen by the Maxillofacial Surgery Service of "Saturnino Lara" provincial hospital in Santiago de Cuba from 1992 to 1996 and this type of lesions represented 6.2% of the fractures treated in this period of time. These lesions were more prevailing in athletes who mainly played ball sports, boxing, basketball, karate and softball.

    Full Text Available El tumor de Pindborg es una neoplasia benigna, rara, con carácter invasivo local y tendencia a la recidiva, que representa entre el 0,17 y el 1,8 % de todos los tumores odontogénicos, del cual tan solo se han publicado unos 200 casos, con una media de 4 casos nuevos por año en el mundo. Se presentó el caso de un hombre de 39 años de edad que acudió a la consulta de cirugía maxilofacial remitido de neurocirugía postraumatismo craneofacial, por presentar un aumento de volumen en el ángulo mandibular derecho. Se tuvo como objetivo publicar la existencia de esta infrecuente neoplasia por lo interesantes que resultan estos tumores por su evolución, dificultad en el diagnóstico, variantes de tratamiento y tendencia a la recidiva. Después de realizar exámenes de laboratorio, radiografías, tomografía axial computarizada y biopsia de fragmento óseo, se obtuvo extensión y diagnóstico de tumor de Pindborg en hemimandíbula derecha. Se realizó la técnica quirúrgica de hemimandibulectomía derecha y reconstrucción con injerto óseo de cresta ilíaca. La evolución del paciente fue satisfactoria.

    Full Text Available El artículo presenta criterios de evaluación para seleccionar las imágenes vinculadas con la práctica de actividad físico-deportiva en la edición de libros de texto de tal forma que estén libres de estereotipos. Los manuales escolares son portadores de un conocimiento que no siempre guarda una relación unívoca con lo que debe ser enseñado. La selección de sus contenidos debería ser coherente con las finalidades del sistema educativo, pero la investigación revela que la edición de los contenidos visuales no se corresponde con la aplicación de criterios que respondan a esa intencionalidad. Tras una aparente neutralidad, las imágenes de los libros de texto enmascaran prejuicios y reproducen desigualdades que afectan a determinados colectivos frágiles. Los criterios de evaluación para la selección de imágenes que se presentan en este trabajo fueron elaborados de acuerdo con los resultados de una investigación que analizó los estereotipos de género, edad, raza, discapacidad y tipología corporal en las imágenes de manuales escolares de educación física para la ESO en España, así como la percepción del alumnado de secundaria sobre una selección significativa de las mismas imágenes. Los criterios elaborados pueden aplicarse para la selección de fotografías destinadas a manuales de diferentes áreas de conocimiento en las que aparezcan representadas personas vinculadas a la práctica de actividad físico-deportiva. La aplicación de los criterios de evaluación se ejemplifica en la selección de contenidos visuales para un hipotético libro de educación física.

    Full Text Available El propósito de la presente investigación es obtener las medidas cefalométricas de mujeres con características faciales agradables en Colombia. Se tomaron radiografías laterales de cráneo a 60 participantes del Concurso Nacional de Belleza entre 1997 y 2001. Cada radiografía se sometió a trazado por dos radiólogos orales y maxilofaciales y los investigadores la digitalizaron con un software de medición cefalométrica. Se analizaron los resultados bajo muestras pareadas de 26 variables en pacientes con anomalías dentomaxilofaciales. De éstas sólo 3 (11.4% coinciden con la norma, en 6 (23.1% hubo diferencias de 1º; 9 (34.7% presentaron diferencia de 2º; 2 (7.7% se diferenciaron en 3º; y 6 (23.1% en más de 4º. No fue significativa la diferencia estadística entre los trazos de las dos radiólogas. Los resultados finales confirman la hipótesis que las medidas cefalométricas en mujeres con características faciales agradables son distintas a las utilizadas de rutina, y muestran una tendencia de compensación alveolodentaria y a una clase II esqueletal.

Constituye un problema de salud en la población de edades pediátricas, pues es la segunda causa más frecuente de ingreso hospitalario en la cirugía maxilofacial, luego de los traumatismos maxilofaciales. Objetivo: describir el comportamiento y el manejo terapéutico por la Atención Primaria de Salud en los municipios de Playa, Marianao y Lisa de La Habana. Métodos: se realizó un estudio observacional retrospectivo en 53 pacientes que fueron ingresados en el Servicio de Cirugía Máxilo Facial del Hospital Pediátrico Docente "Juan Manuel Márquez", desde enero de 2001 a enero de 2007. Resultados: hubo ausencia de significación estadística entre sexos y entre los grupos de edades. La media de la edad fue de 8 años, con una desviación estándar de 4. La celulitis más frecuente fue la odontógena (60,4 %. El 60,3 % de los pacientes fueron mal manejados por la atención primaria. Los grupos dentarios más afectados sugieren que las acciones preventivas deben encaminarse mayormente a la población con dentición temporal y mixta. Conclusiones: hubo mayor representación del sexo masculino y del grupo de 1 a 5 años. El tipo de celulitis facial predominante fue la odontógena. En más de la mitad de los casos el tratamiento antimicrobiano aplicado en la atención primaria de salud fue inadecuado. Al momento del ingreso predominó la evaluación clínica severa.

    2007-09-01

    Full Text Available Uno de los problemas estéticos mas frecuentes y de difícil corrección que afectan el tercio inferior facial, es la disarmonía entre los tejidos blandos y las estructuras óseas subyacentes. Las limitaciones de las técnicas convencionales y los escasos resultados estéticos motivaron al autor a desarrollar un sistema de implantes y una técnica de remodelación tridimensional del maxilar inferior, denominada Sistema Matriz de Implante Mandibular. El sistema Matriz de Implante Mandibular se compone de dos unidades bien definidas: un implante genio-mandibular articulado formado por dos segmentos y un implante de ángulo gonial para cada lado. Esta constituido por material biocompatible poroso de alta densidad que permite su remodelación y adaptación a las necesidades estéticas de cada paciente, además de un ensamblaje perfecto a la superficie ósea. Está indicado especialmente para el embellecimiento del contorno facial y puede realizarse conjuntamente con un lifting o como procedimiento único. También se utiliza en pacientes edéntulos o con micrognatia. El abordaje se realiza a través de una pequeña incisión submentoniana que permite introducir los implantes previa disección subperióstica, bajo visión endoscópica del lecho receptor. La elección final del tamaño, proyección y contorno de los implantes se determina después de colocar implantes de prueba y de tallar los implantes definitivos. Una vez implantado el Sistema Matriz Mandibular, se estabiliza con tornillos de fijación en el tercio anterior de los componentes del implante geniomandibular y además por la superposición del borde posterior de éstos con el borde anterior del implante de ángulo gonial. Este último no necesita fijación, ya que queda contenido entre la cincha ptérigo-masetérica y el maxilar inferior (ángulo gonial. En publicaciones previas se estudiaron las complicaciones en 50 casos, incluyendo: un desplazamiento (corregido con reposicionamiento

    Full Text Available Presentamos una técnica personal que hemos denominado "Face Up", empleando suturas de poliéster dispuestas a través de incisiones mínimas, que permite lograr un rápido efecto lifting para el rejuvenecimiento de la cara. Nuestra experiencia se basa en los resultados del tratamiento de 600 pacientes intervenidos entre septiembre de 2002 y marzo de 2006. Los resultados fueron evidentes desde el postoperatorio inmediato. Las zonas tratadas quedaron firmemente ligadas al plano de anclaje dentro del cuero cabelludo. Se trataron frente, sienes, cejas, mejillas, pómulos, cuello y regiones paramaxilares adyacentes a la zona de los músculos maseteros y bucinadores, que ceden por efecto de la gravedad y del envejecimiento. En las zonas seleccionadas, las suturas se deslizan a través del tejido subcutáneo, donde la aponeurosis de los músculos implicados está firmemente ligada a este plano. Para la intervención se emplea una aguja, llamada "Demax" (aguja biselada con punta en los dos extremos provista de un orificio en uno de ellos para arrastrar la sutura que se inserta desde la región cefálica temporal hasta el punto distal de la zona de la ptosis, donde se efectúa un cambio de sentido formando un bucle que produce el segundo anclaje del tejido, evitando su desplazamiento. La sutura retorna al punto de entrada para su anudamiento al periostio a fin de conseguir y mantener el levantamiento. Las complicaciones recogidas fueron hematomas leves, equímosis, edema, e infección localizada en la incisión de ingreso y nudo de la sutura. En las evaluaciones efectuadas a corto y largo plazo, los resultados fueron buenos con un índice de satisfacción alto por parte de las pacientes y del médico. La técnica "Face Up" es mínimamente traumática y aporta una alternativa al lifting quirúrgico tradicional para el tratamiento del envejecimiento y de la flacidez faciales.We present a personal technique called "Face Up", using polyester sutures

    Full Text Available El nuevo y polémico régimen fiscal de operaciones vinculadas supone un cambio radical respecto de la regulación anterior a la Ley de Prevención del Fraude Fiscal de 2006, y pretende aproximar la normativa fiscal a los criterios expresados por las directrices de la OCDE sobre precios de transferencia, y a la nueva normativa contable, que se inspira en las Normas Internacionales de Contabilidad asumidas por la Unión Europea. Los principales cambios han afectado no solo al concepto de partes vinculadas (que se ha ampliado o la incorporación de los métodos de valoración de la OCDE, sino, sobre todo a: 1.La creación de una nueva obligación de documentación a cargo del obligado tributario que tiene que valorar sus operaciones a valor de mercado; 2.La creación de dos nuevas infracciones tributarias, para asegurar el cumplimiento de la obligación de documentación; 3.La simplificación del procedimiento de comprobación del valor normal de mercado; 4.La regulación expresa del denominado ajuste secundario.

    La asimetría facial es una patología de compromiso funcional y estético que puede estar generado por hiperplasia condilar; el objetivo de esta investigación es determinar la influencia del tamaño condilar en la asimetría facial. Doce sujetos fueron estudiados mediante el análisis de tomografía computadorizada cone beam; todos los pacientes presentaron cintigrama óseo que determino la presencia de hiperplasia condilar activa; el análisis se realizo en un software del sistema de captura modelo Pax Zenith, marca Vatech (Korea 2011), utilizando 90 kV y 120 mA; se obtuvo mediciones de la distancia antero-posterior, superior-inferior y medio-lateral de la cabeza del cóndilo, relacionándose con la posición del cóndilo con la línea mediana facial y la posición de puntos faciales entre incisivos centrales superior e inferior así como con el mentón. Los resultados mostraron un promedio de desvío de mentón de 6,5 mm considerando un cóndilo hiperplásico con un tamaño de 2,7 mm mas que los cóndilos normales. El desvío de incisivo central inferior determinó que por cada 1 mm de desvío dentario existe 2,2 mm de desvío de mentón. El cóndilo hiperplásico fue de mayor tamaño y se posiciono casi 2 mm mas hacia lateral que los cóndilos no hiperplásicos. Es posible concluir que el cóndilo hiperplásico presenta clara influencia en la asimetría facial transversa y es posible estimar una relación de tamaño condilar con grado de asimetría facial.

    2012-01-01

    Introducción: La anastomosis hipogloso-facial es la técnica de elección para la reparación de la parálisis facial cuando no se dispone de un cabo proximal sano del nervio facial. La técnica de anastomosis mediante fresado mastoideo y sección parcial del hipogloso minimiza la atrofia lingual sin sacrificar resultados a nivel facial. Método: La porción mastoidea del nervio facial transcurre por la pared anterior de la AM, a un promedio de 18+/-3 mm de profundidad respecto de la pared lateral. Se debe reconocer la cresta supramastoidea, desde la cual se marca una línea vertical paralela al eje mayor de la AM, 1 cm por detrás de la pared posterior del CAE El fresado se comienza desde la línea medio mastoidea hasta la pared posterior del CAE. Una vez encontrado el nervio facial en el tercio medio del canal mastoideo, el mismo es seguido hacia proximal y distal. Resultados: El abordaje descripto permite acceder al nervio facial intratemporal en su porción mastoidea, y efectuar un fresado óseo sin poner en riesgo al nervio o a estructuras vasculares cercanas. Se trata de un procedimiento técnicamente más sencillo que los abordajes amplios habitualmente utilizados al hueso temporal; no obstante su uso debe ser restringido mayormente a la anastomosis hipogloso-facial. Conclusión: Esta es una técnica relativamente sencilla, que puede ser reproducida por cirujanos sin mayor experiencia en el tema, luego de su paso por el laboratorio de anatomía. PMID:23596555

    Full Text Available Se conoce que la complejidad de las malformaciones congénitas craneofaciales deben tratarse en edades tempranas por medio de un equipo multidisciplinario donde el ortodoncista asume un rol protagónico destacado, aprovechando el potencial de crecimiento y desarrollo de los niños en esta etapa, lo que en ocasiones evita que al llegar a la etapa quirúrgica esta sea menos compleja, tanto para el paciente como para el cirujano. La microsomía hemifacial es una malformación congénita derivada de la alteración del primer y segundo arcos branquiales que puede estar asociada con otros síndromes. Puede existir afección unilateral o bilateral, pero con afectación más severa en uno de los 2 lados, y su etiología es multifactorial. La asimetría facial es una de las características propias de este síndrome, por ello en edades tempranas tratamos de redireccionar el crecimiento con el uso de un aparato funcional híbrido, o sea, adaptado específicamente a las características propias de cada paciente, con el que pueden obtenerse resultados altamente satisfactorios.It is well known that complex congenital craniofacial malformations should be treated at early ages by a multidisciplinary team where the orthodontist takes on a leading role, taking advantage of the potentialities of growth and development of children at this stage, which occasionally makes it possible that the disorder be less complex when reaching the surgical stage, both for the patient and the surgeon. Hemifacial microsomia is a congenital malformation derived from alterations in the first and second brachial arches that might be associated to other syndromes. There can be unilateral or bilateral damage, although the most severe effect is often found in one of the two sides of the face and it has a multi-factor etiology. Facial asymmetry is one of the characteristics inherent to this syndrome, so at early ages, we try to re-direct the growth with the use of a hybrid functional

    Full Text Available En Colombia existe un alto porcentaje de niños y jóvenes que despliegan o son víctimas de conductas agresivas en el contexto escolar. Existe evidencia que muestra que estas conductas están asociadas con dificultades en la regulación emocional y en los procesos de teoría de la mente. Se llevaron a cabo seis estudios de caso a niños entre los 4 y 8 años de edad. A los participantes del estudio se les presentó un cuestionario en donde se planteaban situaciones conflictivas y buscaba fomentar el juego de ficción. Se evaluó la respuesta electrodérmica y las expresiones faciales durante la entrevista. Se presentó una mayor frecuencia de expresiones faciales y cambios en la respuesta electrodérmica cuando la agresión, en las situaciones conflictivas, era intencional y dirigida a un sujeto. Las emociones más frecuentes, registradas en la expresión facial, fueron rabia, tristeza y desprecio. Los resultados de este estudio, sugieren que las expresiones faciales y la respuesta electrodérmica pueden ser medidas interesantes para estudiar la regulación emocional y las conductas agresivas.

    Full Text Available Facial paralysis is an injury that assaults horses, not very unusual in veterinary. It occurs mainly because of direct or indirect traumas over the facial nerve, that goes over the masseter muscle, having only skin an tissue to protect it. Paralyses are common in cases of compression because of the contention of the animal head on the ground. This work reports the case of a PSI mare with four years, that was taken care of in the Veterinarian Hospital of the Veterinary School of the Federal University of Goiás, presenting signs of facial nerve injury; and a cart horse that was taken care at Racecourse of the Pond of Jockey Club of Goiás, with 10 years, debilitated and having facial habronemiasis. These animals received therapy physical, using cinesiotherapy and electrical stimulation, for 60 days, obtaining a satisfactory effect like improve of the left facial muscle, return to symmetrical the left nostril, discreet ptosis in the underling lip, normalization of the action to feed and improve of the facial esthetics. Concluding that therapy physical was a efficient method of treatment injuries in the facial nerve, like compression, helping in the return of the disturbs of muscle function and to the welfare of these animals.

    Full Text Available La teoría de la mente es la capacidad de inferir, predecir y atribuir estados mentales a otras personas. Este constructo ha sido estudiado desde numerosas patologías, como el autismo, la esquizofrenia y el síndrome de down. Estudios recientes han mostrado que las alteraciones de la teoría de la mente pueden ser observadas en los diferentes cuadros clínicos derivados de alteraciones del lóbulo frontal, como la personalidad antisocial. Algunos autores plantean que un aspecto esencial de la teoría de la mente es la empatía. Sin embargo, este constructo no ha sido estudiado en población normal colombiana con conductas violentas y delictivas que han estado vinculadas al conflicto armado. Este artículo tiene como propósito describir algunas características de la tom en sujetos que estuvieron vinculados al conflicto armado en antioquia con manifestaciones sintomáticas relacionadas con comportamientos violentos y delictivos.

    The intratemporal pathway of the facial nerve has been prospectively studied by means of gadolinium MR in 12 patients with a diagnosis of Bell's facial palsy. All the cases presented total facial paralysis and were studied in the acute phase of the disease. With MR, the intratemporal pathway of the facial nerve has been viewed before and after the administration of a paramagnetic contrast medium, revealing uptake involving mainly the labyrinthine segment and the geniculate ganglion in every case. In no case did the MR findings influence the therapeutic approach, nor did they provide information of prognostic value. Therefore, this exploration is not considered necessary in the assessment of typical facial paralyses. The possible advantages of an MR study with contrast medium in facial paralysis specially apply to those cases with atypical clinical presentation, making it possible to establish a positive diagnosis, ruling out other lesions that may have a similar clinical presentantion. Thus, for the time being, a diagnosis of Bell's paralysis is not necessarily an exclusion diagnosis. (Author)

    Full Text Available La translocación del tercio medio facial, técnica consistente en la movilización del esqueleto centrofacial pediculado a los tejidos blandos, ha demostrado permitir un amplio acceso para el abordaje de lesiones situadas en las regiones faciales profundas y la región central de la base del cráneo. Uno de los principales inconvenientes que presentaba este abordaje en niños era la fijación del esqueleto con placas y tornillos de titanio, ya que podía interferir en el crecimiento del hueso en desarrollo. Todo ello planteaba el problema de una segunda intervención para la retirada del material, aumentando, de forma significativa, la morbilidad del procedimiento. Como solución al problema se comercializa, a partir de la década de 1980, el material de osteosíntesis reabsorbible. Presentamos a una paciente de 13 años de edad diagnosticada de un cordoma localizado en el clivus. Como abordaje, se realiza una translocación bilateral del tercio medio facial y se utiliza, para la fijación del esqueleto facial, un nuevo sistema de placas y tornillos reabsorbibles basado en ultrasonidos (Sonic Weld®. KLS Martin, LP, Jacksonville, Florida, USA. Se describen los principales abordajes a las regiones faciales profundas y centromediales de la base del cráneo, las principales variantes de la translocación del tercio medio facial, la técnica de aplicación del nuevo sistema Sonic Weld® y sus diferencias principales respecto a los sistemas reabsorbibles tradicionales.Mid-facial translocation, which involves mobilization of the central facial skeletal structures together with soft tissue pedicles, provides generous access to the anterior and central regions of the skull base. One of the drawbacks of this approach in children is skeletal fixation with titanium osteosynthesis plates and screws, which may affect the growth of developing bone. Consequently, a second intervention is required to remove titanium osteosynthesis material, which increases the

    Facial palsy is a daily challenge for the clinicians. Determining whether facial nerve palsy is peripheral or central is a key step in the diagnosis. Central nervous lesions can give facial palsy which may be easily differentiated from peripheral palsy. The next question is the peripheral facial paralysis idiopathic or symptomatic. A good knowledge of anatomy of facial nerve is helpful. A structure approach is given to identify additional features that distinguish symptomatic facial palsy from idiopathic one. The main cause of peripheral facial palsies is idiopathic one, or Bell's palsy, which remains a diagnosis of exclusion. The most common cause of symptomatic peripheral facial palsy is Ramsay-Hunt syndrome. Early identification of symptomatic facial palsy is important because of often worst outcome and different management. The prognosis of Bell's palsy is on the whole favorable and is improved with a prompt tapering course of prednisone. In Ramsay-Hunt syndrome, an antiviral therapy is added along with prednisone. We also discussed of current treatment recommendations. We will review short and long term complications of peripheral facial palsy.

    Dermatologic problems of the face affect both function and aesthetics, which are based on complex anatomical features. Treating dermatologic problems while preserving the aesthetics and functions of the face requires knowledge of normal anatomy. When performing successfully invasive procedures of the face, it is essential to understand its underlying topographic anatomy. This chapter presents the anatomy of the facial musculature and neurovascular structures in a systematic way with some clinically important aspects. We describe the attachments of the mimetic and masticatory muscles and emphasize their functions and nerve supply. We highlight clinically relevant facial topographic anatomy by explaining the course and location of the sensory and motor nerves of the face and facial vasculature with their relations. Additionally, this chapter reviews the recent nomenclature of the branching pattern of the facial artery.

    Full Text Available Blindsight denotes unconscious residual visual capacities in the context of an inability to consciously recollect or identify visual information. It has been described for color and shape discrimination, movement or facial emotion recognition. The present study investigates a patient suffering from cortical blindness whilst maintaining select residual abilities in face detection. Our patient presented the capacity to distinguish between jumbled/normal faces, known/unknown faces or famous people’s categories although he failed to explicitly recognize or describe them. Conversely, performance was at chance level when asked to categorize non-facial stimuli. Our results provide clinical evidence for the notion that some aspects of facial processing can occur without perceptual awareness, possibly using direct tracts from the thalamus to associative visual cortex, bypassing the primary visual cortex.

    Full Text Available El envejecimiento facial es un proceso único y particular a cada individuo y está regido en especial por su carga genética. El lifting facial es una compleja técnica desarrollada en nuestra especialidad desde principios de siglo, para revertir los principales signos de este proceso. Los factores secundarios que gravitan en el envejecimiento facial son múltiples y por ello las ritidectomías o lifting cérvico faciales descritas han buscado corregir los cambios fisonómicos del envejecimiento excursionando, como se describe, en todos los planos tisulares involucrados. Esta cirugía por lo tanto, exige conocimiento cabal de la anatomía quirúrgica, pericia y experiencia para reducir las complicaciones, estigmas quirúrgicos y revisiones secundarias. La ridectomía facial ha evolucionado hacia un procedimiento más simple, de incisiones más cortas y disecciones menos extensas. Las suspensiones musculares han variado en su ejecución y los vectores de montaje y resección cutánea son cruciales en los resultados estéticos de la cirugía cérvico facial. Hoy estos vectores son de tracción más vertical. La corrección de la flaccidez va acompañada de un interés en reponer el volumen de la superficie del rostro, en especial el tercio medio. Las técnicas quirúrgicas de rejuvenecimiento, en especial el lifting facial, exigen una planificación para cada paciente. Las técnicas adjuntas al lifting, como blefaroplastias, mentoplastía, lipoaspiración de cuello, implantes faciales y otras, también han tenido una positiva evolución hacia la reducción de riesgos y mejor éxito estético.

Advances in facial reanimation over the past 4 decades have given rise to new treatments designed to restore balance and function in pediatric patients with facial paralysis. This article provides a comprehensive review of pediatric facial rehabilitation and describes a zone-based approach to assessment and treatment of impaired facial movement.

El análisis cinemático llevado a cabo a partir de fallas y zonas de cizalla frágil-dúctil en cuatro localidades (El Dorado- Monserrat, Norte de Cerro Vanguardia y El Fénix, en la comarca del Deseado; y Lago Ghío, en la Cordillera Patagónica Austral, permitió definir los ejes cinemáticos de la deformación jurásica, reconocer dos eventos cinemáticos diferentes (principal y secundario e identificar la existencia de un régimen transtensional. En relación a la oblicuidad que presentan los ejes cinemáticos en estas localidades, se definieron en forma preliminar dos dominios: el oriental y el occidental. El dominio oriental (El Dorado - Monserrat, Norte de Cerro Vanguardia presenta una dirección de extensión ENE para el evento principal y NNO para el evento secundario, mientras que el dominio occidental (El Fénix y Lago Ghío exhibe direcciones de extensión NE y NO para los episodios principal y secundario, respectivamente. Estos eventos cinemáticos diferentes (principal y secundario guardan estrecha correlación con facies volcánicas definidas, ya que el episodio secundario se encuentra temporalmente restringido al momento del emplazamiento de la facies efusiva riolítica (domos, coladas, cuerpos hipabisales. Dado el marcado diacronismo de esta provincia volcánica, las diferencias estructurales y cinemáticas halladas entre ambos dominios podrían estar reflejando un emplazamiento controlado por estructuras desarrolladas progresivamente que, a escala continental, estarían vinculadas a un régimen de deformación no-coaxial mayor.

    Facial reanimation following persistent facial paralysis can be managed with surgical procedures of varying complexity. The choice of the technique is mainly determined by the cause of facial paralysis, the age and desires of the patient. The techniques most commonly used are the nerve grafts (VII-VII, XII-VII, cross facial graft), dynamic muscle transfers (temporal myoplasty, free muscle transfert) and static suspensions. An intensive rehabilitation through specific exercises after all procedures is essential to archieve good results.

    A 34-year-old man from El Salvador was referred to our clinic with a 10-year history of a pruritic erythematous facial eruption. He reported increased pruritus and scaling of lesions when exposed to the sun. He worked as a construction worker and admitted to frequent sun exposure. Physical examination revealed well-circumscribed erythematous to violaceous papules with raised borders and atrophic centers localized to the nose (Figure 1). He did not have lesions on the arms or legs. He did not report a family history of similar lesions. A biopsy specimen was obtained from the edge of a lesion on the right ala. Histologic examination of the biopsy specimen showed acanthosis of the epidermis with focal invagination of the corneal layer and a homogeneous column of parakeratosis in the center of that layer consistent with a cornoid lamella (Figure 2). Furthermore, the granular layer was absent at the cornoid lamella base. The superficial dermis contained a sparse, perivascular lymphocytic infiltrate. No evidence of dysplasia or malignancy was seen. These findings supported a diagnosis of porokeratosis. The patient underwent a trial of cryotherapy with moderate improvement of the facial lesions.

    Full Text Available During their lifetime, people learn to recognize thousands of faces that they interact with. Face perception refers to an individual's understanding and interpretation of the face, particularly the human face, especially in relation to the associated information processing in the brain. The proportions and expressions of the human face are important to identify origin, emotional tendencies, health qualities, and some social information. From birth, faces are important in the individual's social interaction. Face perceptions are very complex as the recognition of facial expressions involves extensive and diverse areas in the brain. Our main goal is to put emphasis on presenting human faces specialized studies, and also to highlight the importance of attractiviness in their retention. We will see that there are many factors that influence face recognition.

    Facial palsy can be defined as a decrease in function of the facial nerve, the primary motor nerve of the facial muscles. When the facial palsy is peripheral, it affects both the superior and inferior areas of the face as opposed to central palsies, which affect only the inferior portion. The main cause of peripheral facial palsies is Bell's palsy, which remains a diagnosis of exclusion. The prognosis is good in most cases. In cases with significant cosmetic sequelae, a variety of surgical procedures are available (such as hypoglossal-facial anastomosis, temporalis myoplasty and Tenzel external canthopexy) to rehabilitate facial aesthetics and function.

    The management of facial paralysis is one of the most complex areas of reconstructive surgery. Given the wide variety of functional and cosmetic deficits in the facial paralysis patient, the reconstructive surgeon requires a thorough understanding of the surgical techniques available to treat this condition. This review article will focus on surgical management of facial paralysis and the treatment options available for acute facial paralysis (facial paralysis (3 weeks to 2 yr) and chronic facial paralysis (>2 yr). For acute facial paralysis, the main surgical therapies are facial nerve decompression and facial nerve repair. For facial paralysis of intermediate duration, nerve transfer procedures are appropriate. For chronic facial paralysis, treatment typically requires regional or free muscle transfer. Static techniques of facial reanimation can be used for acute, intermediate, or chronic facial paralysis as these techniques are often important adjuncts to the overall management strategy.

    2014-04-01

    The facial nerve is the most commonly paralyzed nerve in the human body. Facial paralysis affects aesthetic appearance, and it has a profound effect on function and quality of life. Management of patients with facial paralysis requires a multidisciplinary approach, including otolaryngologists, plastic surgeons, ophthalmologists, and physical therapists. Regardless of etiology, patients with facial paralysis should be evaluated systematically, with initial efforts focused upon establishing proper diagnosis. Management should proceed with attention to facial zones, including the brow and periocular region, the midface and oral commissure, the lower lip and chin, and the neck. To effectively compare contemporary facial reanimation strategies, it is essential to employ objective intake assessment methods, and standard reassessment schemas during the entire management period.

    Extracranial infiltration of the facial nerve by salivary gland tumors is the most frequent cause of facial palsy secondary to malignancy. Nevertheless, facial palsy related to salivary gland cancer is uncommon. Therefore, reconstructive facial reanimation surgery is not a routine undertaking for most head and neck surgeons. The primary aims of facial reanimation are to restore tone, symmetry, and movement to the paralyzed face. Such restoration should improve the patient's objective motor function and subjective quality of life. The surgical procedures for facial reanimation rely heavily on long-established techniques, but many advances and improvements have been made in recent years. In the past, published experiences on strategies for optimizing functional outcomes in facial paralysis patients were primarily based on small case series and described a wide variety of surgical techniques. However, in the recent years, larger series have been published from high-volume centers with significant and specialized experience in surgical and nonsurgical reanimation of the paralyzed face that have informed modern treatment. This chapter reviews the most important diagnostic methods used for the evaluation of facial paralysis to optimize the planning of each individual's treatment and discusses surgical and nonsurgical techniques for facial rehabilitation based on the contemporary literature.

    Facial tics and spasms are socially incapacitating, but effective treatment is often available. The clinical picture is sufficient for distinguishing between the different diseases that cause this affliction.We describe three cases of patients with facial tics or spasms: one case of tics, which are familiar to many physicians; one case of blepharospasms; and one case of hemifacial spasms. We discuss the differential diagnosis and the treatment possibilities for facial tics and spasms. Early diagnosis and treatment is important, because of the associated social incapacitation. Botulin toxin should be considered as a treatment option for facial tics and a curative neurosurgical intervention should be considered for hemifacial spasms.

    2012-01-01

    Full Text Available En los estudios sobre economía espacial y economía industrial suele afirmarse que la desindustrialización consiste en la pérdida de importancia de la industria manufacturera en el mercado de trabajo y en la estructura económica. Los factores asociados a dicha pérdida se dividen entre los vinculados con la integración vertical de los servicios de orden superior al proceso productivo, y los relacionados con la falta de competitividad para la producción de bienes. El propósito de este artículo consiste en aportar elementos conceptuales y evidencia empírica para caracterizar la desindustrialización como un proceso que atraviesa por diversas fases, que van desde el crecimiento industrial hasta la pérdida absoluta de empleo y producción; asimismo busca explorar variables asociadas a tal proceso. Para ello se utilizan los instrumentos estadísticos de análisis de correspondencias, los modelos log-lineales y las funciones de regresión logística. En una primera etapa el estudio incluye 88 países, y en la segunda se cambia la escala geográfica para enfocarse en las 90 áreas urbanas y metropolitanas más pobladas de México. Se concluye que la desindustrialización en ambas escalas territoriales (país y ciudad comparte elementos comunes relacionados con un menor crecimiento económico y un mayor peso de los servicios al productor. Pero también se observan especificidades, como la mayor velocidad y variabilidad del proceso en las ciudades respecto a los países. La desindustrialización debe ser vista como un proceso, aunque no siempre lineal ni tampoco circunscrito a las naciones más desarrolladas o a las ciudades de mayor tamaño.

    Ghent, John; McDonald, J.

    2005-06-01

    This paper details a procedure for classifying facial expressions. This is a growing and relatively new type of problem within computer vision. One of the fundamental problems when classifying facial expressions in previous approaches is the lack of a consistent method of measuring expression. This paper solves this problem by the computation of the Facial Expression Shape Model (FESM). This statistical model of facial expression is based on an anatomical analysis of facial expression called the Facial Action Coding System (FACS). We use the term Action Unit (AU) to describe a movement of one or more muscles of the face and all expressions can be described using the AU's described by FACS. The shape model is calculated by marking the face with 122 landmark points. We use Principal Component Analysis (PCA) to analyse how the landmark points move with respect to each other and to lower the dimensionality of the problem. Using the FESM in conjunction with Support Vector Machines (SVM) we classify facial expressions. SVMs are a powerful machine learning technique based on optimisation theory. This project is largely concerned with statistical models, machine learning techniques and psychological tools used in the classification of facial expression. This holistic approach to expression classification provides a means for a level of interaction with a computer that is a significant step forward in human-computer interaction.

  1. Live facial feature extraction

    Institute of Scientific and Technical Information of China (English)

    ZHAO JieYu

    2008-01-01

    Precise facial feature extraction is essential to the high-level face recognition and expression analysis. This paper presents a novel method for the real-time geomet-ric facial feature extraction from live video. In this paper, the input image is viewed as a weighted graph. The segmentation of the pixels corresponding to the edges of facial components of the mouth, eyes, brows, and nose is implemented by means of random walks on the weighted graph. The graph has an 8-connected lattice structure and the weight value associated with each edge reflects the likelihood that a random walker will cross that edge. The random walks simulate an anisot-ropic diffusion process that filters out the noise while preserving the facial expres-sion pixels. The seeds for the segmentation are obtained from a color and motion detector. The segmented facial pixels are represented with linked lists in the origi-nal geometric form and grouped into different parts corresponding to facial com-ponents. For the convenience of implementing high-level vision, the geometric description of facial component pixels is further decomposed into shape and reg-istration information. Shape is defined as the geometric information that is invari-ant under the registration transformation, such as translation, rotation, and iso-tropic scale. Statistical shape analysis is carried out to capture global facial fea-tures where the Procrustes shape distance measure is adopted. A Bayesian ap-proach is used to incorporate high-level prior knowledge of face structure. Ex-perimental results show that the proposed method is capable of real-time extraction of precise geometric facial features from live video. The feature extraction is robust against the illumination changes, scale variation, head rotations, and hand inter-ference.

  9. Simultaneous facial feature tracking and facial expression recognition.

    2013-07-01

    The tracking and recognition of facial activities from images or videos have attracted great attention in computer vision field. Facial activities are characterized by three levels. First, in the bottom level, facial feature points around each facial component, i.e., eyebrow, mouth, etc., capture the detailed face shape information. Second, in the middle level, facial action units, defined in the facial action coding system, represent the contraction of a specific set of facial muscles, i.e., lid tightener, eyebrow raiser, etc. Finally, in the top level, six prototypical facial expressions represent the global facial muscle movement and are commonly used to describe the human emotion states. In contrast to the mainstream approaches, which usually only focus on one or two levels of facial activities, and track (or recognize) them separately, this paper introduces a unified probabilistic framework based on the dynamic Bayesian network to simultaneously and coherently represent the facial evolvement in different levels, their interactions and their observations. Advanced machine learning methods are introduced to learn the model based on both training data and subjective prior knowledge. Given the model and the measurements of facial motions, all three levels of facial activities are simultaneously recognized through a probabilistic inference. Extensive experiments are performed to illustrate the feasibility and effectiveness of the proposed model on all three level facial activities.

    2010-01-01

    The Facial Action Coding System (FACS) [23] is an objective method for quantifying facial movement in terms of component actions. This system is widely used in behavioral investigations of emotion, cognitive processes, and social interaction. The coding is presently performed by highly trained human experts. This paper explores and compares techniques for automatically recognizing facial actions in sequences of images. These techniques include analysis of facial motion through estimation of optical flow; holistic spatial analysis, such as principal component analysis, independent component analysis, local feature analysis, and linear discriminant analysis; and methods based on the outputs of local filters, such as Gabor wavelet representations and local principal components. Performance of these systems is compared to naive and expert human subjects. Best performances were obtained using the Gabor wavelet representation and the independent component representation, both of which achieved 96 percent accuracy for classifying 12 facial actions of the upper and lower face. The results provide converging evidence for the importance of using local filters, high spatial frequencies, and statistical independence for classifying facial actions. PMID:21188284

    Introduccion. La percepcion de caras involucra una amplia red de conexiones entre regiones corticales y subcorticales que intercambian y sincronizan informacion a traves de haces de sustancia blanca. Este preciso sistema de comunicacion puede verse afectado tanto a traves de las propias estructuras como por las vias que las conectan. Objetivos. Delimitar el sustrato neuronal que subyace a la percepcion de la expresion facial y analizar los diferentes factores que participan modulando la integridad de esta red neuronal, con el fin de proponer mejoras en los programas de rehabilitacion. Desarrollo. Cuando la compleja red de conexiones que participa en la percepcion de la expresion facial se altera por traumatismos, patologias neurodegenerativas, trastornos del desarrollo, incluso por aislamiento social o contextos negativos, se deteriora tambien la capacidad para interactuar de manera adaptativa con el entorno. Conclusiones. La posibilidad de restaurar la integridad de la red neuronal encargada del procesamiento de la expresion facial pasa por tener en cuenta diferentes variables que en mayor o menor grado se han mostrado capaces de modificar la estructura o funcionalidad de las redes neuronales, como el entrenamiento aerobico, la estimulacion magnetica transcraneal, la estimulacion electrica transcraneal y el aprendizaje, sin bien estas variables estarian condicionadas por la edad, el tipo y evolucion del trastorno o el contexto generador, lo que plantearia la necesidad de protocolos de rehabilitacion ajustados y orientados a delimitar el sustrato neuronal del deficit.

    A 14-year-old patient had a low-energy facial blunt trauma that evolved to right facial paralysis caused by parotid hematoma with parotid salivary gland lesion. Computed tomography and angiography demonstrated intraparotid collection without pseudoaneurysm and without radiologic signs of fracture in the face. The patient was treated with serial punctures for hematoma deflation, resolving with regression and complete remission of facial paralysis, with no late sequela. The authors discuss the relationship between facial nerve traumatic injuries associated or not with the presence of facial fractures, emphasizing the importance of early recognition and appropriate treatment of such cases.

This was a cross-sectional study with 286 randomly selected from Universiti Sains Malaysia (USM) Health Campus students (150 females and 136 males; 100 Malaysian Chinese, 100 Malaysian Malay and 86 Malaysian Indian), with the mean age of 21.54 ± 1.56 (Age range, 18-25). Facial indices obtained from direct facial measurements were used for the classification of facial shape into short, ideal and long. A validated structured questionnaire was used to assess subjects' evaluation of their own facial appearance. The mean facial indices of Malaysian Indian (MI), Malaysian Chinese (MC) and Malaysian Malay (MM) were 1.59 ± 0.19, 1.57 ± 0.25 and 1.54 ± 0.23 respectively. Only MC showed significant sexual dimorphism in facial index (P = 0.047; Pmean score of 2.18 ± 0.97 for overall impression and 2.15 ± 1.04 for facial parts, compared to MM and MI, with mean score of 1.80 ± 0.97 and 1.64 ± 0.74 respectively for overall impression; 1.75 ± 0.95 and 1.70 ± 0.83 respectively for facial parts. 1) Only 17.1% of Malaysian facial proportion conformed to the golden ratio, with majority of the population having short face (54.5%); 2) Facial index did not depend significantly on races; 3) Significant sexual dimorphism was shown among Malaysian Chinese; 4) All three races are generally satisfied with their own facial appearance; 5) No significant association was found between golden ratio and facial evaluation score among Malaysian population.

  14. Retinotopy of facial expression adaptation.

    2014-01-01

    The face aftereffect (FAE; the illusion of faces after adaptation to a face) has been reported to occur without retinal overlap between adaptor and test, but recent studies revealed that the FAE is not constant across all test locations, which suggests that the FAE is also retinotopic. However, it remains unclear whether the characteristic of the retinotopy of the FAE for one facial aspect is the same as that of the FAE for another facial aspect. In the research reported here, an examination of the retinotopy of the FAE for facial expression indicated that the facial expression aftereffect occurs without retinal overlap between adaptor and test, and depends on the retinal distance between them. Furthermore, the results indicate that, although dependence of the FAE on adaptation-test distance is similar between facial expression and facial identity, the FAE for facial identity is larger than that for facial expression when a test face is presented in the opposite hemifield. On the basis of these results, I discuss adaptation mechanisms underlying facial expression processing and facial identity processing for the retinotopy of the FAE.

    2014-01-01

    Facial expressions reflect internal emotional states of a character or in response to social communications. Though much effort has been taken to generate realistic facial expressions, it still remains a challenging topic due to human being's sensitivity to subtle facial movements. In this paper, we present a method for facial animation generation, which reflects true facial muscle movements with high fidelity. An intermediate model space is introduced to transfer captured static AU peak frames based on FACS to the conformed target face. And then dynamic parameters derived using a psychophysics method is integrated to generate facial animation, which is assumed to represent natural correlation of multiple AUs. Finally, the animation sequence in the intermediate model space is mapped to the target face to produce final animation.

Included are occipital neuralgia, superior laryngeal neuralgia, auriculotemporal neuralgia, glossopharyngeal and nervus intermedius neuralgia, and pain from acute herpes zoster and postherpetic neuralgia of the trigeminal and intermedius nerves. Problem Facial neuralgias are rare and many physicians do not see such cases in their lifetime, so patients with a suspected diagnosis within this group should be referred to a specialized center where multidisciplinary team diagnosis may be available. Potential solution Each facial neuralgia can be identified on the basis of clinical presentation, allowing for precision diagnosis and planning of treatment. Treatment remains conservative with oral or topical medication recommended for neuropathic pain to be tried before more invasive procedures are undertaken. However, evidence for efficacy of current treatments remains weak.

  18. Facial resemblance enhances trust.

    Organisms are expected to be sensitive to cues of genetic relatedness when making decisions about social behaviour. Relatedness can be assessed in several ways, one of which is phenotype matching: the assessment of similarity between others' traits and either one's own traits or those of known relatives. One candidate cue of relatedness in humans is facial resemblance. Here, I report the effects of an experimental manipulation of facial resemblance in a two-person sequential trust game. Subjects were shown faces of ostensible playing partners manipulated to resemble either themselves or an unknown person. Resemblance to the subject's own face raised the incidence of trusting a partner, but had no effect on the incidence of selfish betrayals of the partner's trust. Control subjects playing with identical pictures failed to show such an effect. In a second experiment, resemblance of the playing partner to a familiar (famous) person had no effect on either trusting or betrayals of trust.

    2014-04-01

    This paper reviews clinical neuropsychological studies that have indicated that the recognition of a person's identity and the recognition of facial expressions are processed by different cortical and subcortical areas of the brain. The fusiform gyrus, especially the right fusiform gyrus, plays an important role in the recognition of identity. The superior temporal sulcus, amygdala, and medial frontal cortex play important roles in facial-expression recognition. Both facial recognition and facial-expression recognition are highly intellectual processes that involve several regions of the brain.

    Full Text Available Facial reconstructions in archaeology allow empathy with people who lived in the past and enjoy considerable popularity with the public. It is a common misconception that facial reconstruction will produce an exact likeness; a resemblance is the best that can be hoped for. Research at Sheffield University is aimed at the development of a computer system for facial reconstruction that will be accurate, rapid, repeatable, accessible and flexible. This research is described and prototypical 3-D facial reconstructions are presented. Interpolation models simulating obesity, ageing and ethnic affiliation are also described. Some strengths and weaknesses in the models, and their potential for application in archaeology are discussed.

    Premise Facial pain refers to a heterogeneous group of clinically and etiologically different conditions with the common clinical feature of pain in the facial area. Among these conditions, trigeminal neuralgia (TN), persistent idiopathic facial pain, temporomandibular joint pain, and trigeminal autonomic cephalalgias (TAC) are the most well described conditions. Conclusion TN has been known for centuries, and is recognised by its characteristic and almost pathognomonic clinical features. The other facial pain conditions are less well defined, and over the years there has been confusion about their classification. PMID:28181442

  11. Cephalometric soft tissue facial analysis.

    Science.gov (United States)

    Bergman, R T

    1999-10-01

    My objective is to present a cephalometric-based facial analysis to correlate with an article that was published previously in the American Journal of Orthodontic and Dentofacial Orthopedics. Eighteen facial or soft tissue traits are discussed in this article. All of them are significant in successful orthodontic outcome, and none of them depend on skeletal landmarks for measurement. Orthodontic analysis most commonly relies on skeletal and dental measurement, placing far less emphasis on facial feature measurement, particularly their relationship to each other. Yet, a thorough examination of the face is critical for understanding the changes in facial appearance that result from orthodontic treatment. A cephalometric approach to facial examination can also benefit the diagnosis and treatment plan. Individual facial traits and their balance with one another should be identified before treatment. Relying solely on skeletal analysis, assuming that the face will balance if the skeletal/dental cephalometric values are normalized, may not yield the desired outcome. Good occlusion does not necessarily mean good facial balance. Orthodontic norms for facial traits can permit their measurement. Further, with a knowledge of standard facial traits and the patient's soft tissue features, an individualized norm can be established for each patient to optimize facial attractiveness. Four questions should be asked regarding each facial trait before treatment: (1) What is the quality and quantity of the trait? (2) How will future growth affect the trait? (3) How will orthodontic tooth movement affect the existing trait (positively or negatively)? (4) How will surgical bone movement to correct the bite affect the trait (positively or negatively)?

    The remodeling process of synapses and eurotransmitter receptors of facial nucleus were observed. Models were set up by facial-facial anastomosis in rat. At post-surgery day (PSD) 0, 7, 21 and 60, synaptophysin (p38), NMDA receptor subunit 2A and AMPA receptor subunit 2 (GIuR2) were observed by immunohistochemical method and emi-quantitative RT-PCR, respectively. Meanwhile, the synaptic structure of the facial motorneurons was observed under a transmission electron microscope (TEM). The intensity of p38 immunoreactivity was decreased, reaching the lowest value at PSD day 7, and then increased slightly at PSD 21. Ultrastructurally, the number of synapses in nucleus of the operational side decreased, which was consistent with the change in P38 immhnoreactivity. NMDAR2A mRNA was down-regulated significantly in facial nucleus after the operation (P000.05). The synapses innervation and the expression of NMDAR2A and AMPAR2 mRNA in facial nucleus might be modified to suit for the new motor tasks following facial-facial anastomosis, and influenced facial nerve regeneration and recovery.

    Ma, Fengling; Xu, Fen; Luo, Xianming

    2016-01-01

    This study examined developmental changes in children's abilities to make trustworthiness judgments based on faces and the relationship between a child's perception of trustworthiness and facial attractiveness. One hundred and one 8-, 10-, and 12-year-olds, along with 37 undergraduates, were asked to judge the trustworthiness of 200 faces. Next, they issued facial attractiveness judgments. The results indicated that children made consistent trustworthiness and attractiveness judgments based on facial appearance, but with-adult and within-age agreement levels of facial judgments increased with age. Additionally, the agreement levels of judgments made by girls were higher than those by boys. Furthermore, the relationship between trustworthiness and attractiveness judgments increased with age, and the relationship between two judgments made by girls was closer than those by boys. These findings suggest that face-based trait judgment ability develops throughout childhood and that, like adults, children may use facial attractiveness as a heuristic cue that signals a stranger's trustworthiness.

    Rehabilitation takes an important part in the treatment of facial paralysis, especially when these are severe. It aims to lead the recovery of motor activity and prevent or reduce sequelae like synkinesis or spasms. It is preferable that it be proposed early in order to set up a treatment plan based on the results of the assessment, sometimes coupled with an electromyography. In case of surgery, preoperative work is recommended, especially in case of hypoglossofacial anastomosis or lengthening temporalis myoplasty (LTM). Our proposal is to present an original technique to enhance the sensorimotor loop and the cortical control of movement, especially when using botulinum toxin and after surgery.

  16. Processing faces and facial expressions.

    Science.gov (United States)

    Posamentier, Mette T; Abdi, Hervé

    2003-09-01

    This paper reviews processing of facial identity and expressions. The issue of independence of these two systems for these tasks has been addressed from different approaches over the past 25 years. More recently, neuroimaging techniques have provided researchers with new tools to investigate how facial information is processed in the brain. First, findings from "traditional" approaches to identity and expression processing are summarized. The review then covers findings from neuroimaging studies on face perception, recognition, and encoding. Processing of the basic facial expressions is detailed in light of behavioral and neuroimaging data. Whereas data from experimental and neuropsychological studies support the existence of two systems, the neuroimaging literature yields a less clear picture because it shows considerable overlap in activation patterns in response to the different face-processing tasks. Further, activation patterns in response to facial expressions support the notion of involved neural substrates for processing different facial expressions.

    Facial expression recognition consists of determining what kind of emotional content is presented in a human face.The problem presents a complex area for exploration, since it encompasses face acquisition, facial feature tracking, facial expression classification. Facial feature tracking is of the most interest. Active Appearance Model (AAM) enables accurate tracking of facial features in real-time, but lacks occlusions and self-occlusions. In this paper we propose a solution to improve the accuracy of fitting technique. The idea is to include occluded images into AAM training data. We demonstrate the results by running ex periments using gradient descent algorithm for fitting the AAM. Our experiments show that using fitting algorithm with occluded training data improves the fitting quality of the algorithm.

    This report is about facial asymmetry, its connection to emotional expression, and methods of measuring facial asymmetry in videos of faces. The research was motivated by two factors: firstly, there was a real opportunity to develop a novel measure of asymmetry that required minimal human involvement and that improved on earlier measures in the literature; and secondly, the study of the relationship between facial asymmetry and emotional expression is both interesting in its own right, and important because it can inform neuropsychological theory and answer open questions concerning emotional processing in the brain. The two aims of the research were: first, to develop an automatic frame-by-frame measure of facial asymmetry in videos of faces that improved on previous measures; and second, to use the measure to analyse the relationship between facial asymmetry and emotional expression, and connect our findings with previous research of the relationship.

    Full Text Available A paralisia facial causada pelo colesteatoma é pouco freqüente. As porções do nervo mais acometidas são a timpânica e a região do 2º joelho. Nos casos de disseminação da lesão colesteatomatosa para o epitímpano anterior, o gânglio geniculado é o segmento do nervo facial mais sujeito à injúria. A etiopatogenia pode estar ligada à compressão do nervo pelo colesteatoma seguida de diminuição do seu suprimento vascular como também pela possível ação de substâncias neurotóxicas produzidas pela matriz do tumor ou pelas bactérias nele contidas. OBJETIVO: Avaliar a incidência, as características clínicas e o tratamento da paralisia facial decorrente da lesão colesteatomatosa. FORMA DE ESTUDO: Clínico retrospectivo. MATERIAL E MÉTODO: Estudo retrospectivo envolvendo dez casos de paralisia facial por colesteatoma selecionados através de levantamento de 206 descompressões do nervo facial com diferentes etiologias, realizadas na UNIFESP-EPM nos últimos dez anos.

    The purpose of this prospective study was to define the enhancement pattern of the facial nerve in idiopathic facial paralysis (Bell`s palsy) on magnetic resonance (MR) imaging with routine doses of gadolinium-DTPA (0.1 mmol/kg). Using 0.5 T imager, 24 patients were examined with a mean interval time of 13.7 days between the onset of symptoms and the MR examination. Contralateral asymptomatic facial nerves constituted the control group and five of the normal facial nerves (20.8%) showed enhancement confined to the geniculate ganglion. Hence, contrast enhancement limited to the geniculate ganglion in the abnormal facial nerve (3 of 24) was referred to a equivocal. Not encountered in any of the normal facial nerves, enhancement of other segments alone or associated with geniculate ganglion enhancement was considered to be abnormal and noted in 70.8% of the symptomatic facial nerves. The most frequently enhancing segments were the geniculate ganglion and the distal intracanalicular segment. (orig.)

    Full Text Available OBJETIVO: avaliar a prevalência do HIV nas parturientes de maternidades vinculadas ao SUS, pela utilização do teste rápido. MÉTODOS: estudo transversal realizado em maternidades conveniadas ao SUS no Estado de Sergipe, após treinamento realizado com os profissionais de saúde dessas maternidades. As parturientes foram submetidas ao teste rápido imunocromatográfico para HIV, independente de já o terem realizado no pré-natal, após aconselhamento e assinatura do termo de consentimento livre e esclarecido. O teste utilizado foi DetermineTM - Abbott Laboratórios do Brasil. Utilizou-se o esquema de profilaxia da transmissão vertical para todos os casos, segundo o protocolo recomendado pelo Ministério da Saúde. Foi criado banco de dados no Epi-Info 2002 e calculada a prevalência em relação a todos os testes realizados no período de janeiro de 2003 a março de 2004, por meio de análise estatística descritiva. RESULTADO: após realização de 9.215 testes rápidos, foram detectadas 39 (0,42% soropositivas para HIV, das quais 23 (59% não conheciam a sua soropositividade. Duas gestantes que já eram sabidamente HIV positivas não relataram aos profissionais sua condição no momento da admissão. O número de parturientes que referiram ter freqüentado o serviço de pré-natal foi alto (89%, mas somente 32,5% destas foram submetidas ao teste para HIV na gestação. CONCLUSÃO: a prevalência detectada (0,42% neste estudo é semelhante à nacional. É alta a prevalência de parturientes que desconhecem sua soropositividade para HIV, o que indica inadequado funcionamento de cuidados pré-natais dispensados. Na situação atual é necessária a triagem no momento do parto, para garantia de intervenções adequadas neste momento crucial da transmissão do HIV.PURPOSE: to evaluate the prevalence of HIV infection in parturient women from maternity hospitals linked to the Public Health Service in Sergipe state (Brazil using the rapid test

    Full Text Available Las ciudades actuales están sufriendo fuertes procesos de transformación vinculados a la paulatina retirada del Estado de la planificación urbana y al rol activo que toma el mercado en la distribución y usos espaciales. Una manifestación de estas transformaciones son los barrios cerrados . El presente artículo es una revisión de antecedentes empíricos y conceptuales relacionados con estos barrios, cuya masificación obliga a repensar las nociones de segregación y fragmentación espacial en las ciudades de hoy. Con esta revisión se pueden entender los criterios de localización, la integración funcional con el entorno y las explicaciones dadas a la aparición y expansión de estos barrios en las ciudades. El desafío a futuro es profundizar en las subjetividades espaciales que conviven en estos espacios.

    Full Text Available Un hecho reciente que ha causado revuelo en la comunidad médica internacional ha sido la noticia de la realización del primer trasplante parcial de cara en Francia. Con este hecho se ha vuelto a poner sobre el tapete un tema que desde el punto de vista médico, psicosocial y ético ha generado polémica. Asimismo, puede tener implicaciones desde el enfoque medicolegal. Los trasplantes han tenido un desarrollo vertiginoso desde los inicios del siglo XX, desarrollando técnicas microquirúrgicas y fármacos inmunomoduladores capaces de garantizar un alto porcentaje de éxito. Sin embargo en este momento el trasplante facial estaría indicado para un reducido número de casos con severas lesiones faciales en los cuales las técnicas convencionales no ofreciesen más ayuda. Además los pacientes tendrían que dar su consentimiento informado a un procedimiento que aún está en fase experimental y del cual no se conocen con certeza las consecuencias a corto, mediano y largo plazo. Desde el punto de vista medicolegal implicaría principalmente la modificación de la evolución usual de los estados secuelares funcionales y estéticos del rostro.A recent fact that has caused commotion in the international medical community has been the news of first partial face transplantation executed in France. With this fact, this theme has been put again on the covering. Since the medical, psychosocial and ethical point of view, it has generated polemics. Likewise, it can have medicolegal implications. The transplants have had a giddy development since the starts of the 20th century, when were developed microsurgical techniques and then inmunosuppressant drugs. With both there was a high percentage of transplant success. Nevertheless, at this time, the facial transplant would be indicated for a reduced number of patients with severe facial wounds, in which the conventional techniques don’t offer more helps. Also, it is necessary that the patients give their

    Full Text Available Accidental injury to the facial nerve where the bony canal defects are present may result with facial nerve dysfunction during otological surgery. Therefore, it is critical to know the incidence and the type of facial nerve dehiscences in the presence of normal development of the facial canal. The aim of this study is to review the site and the type of such bony defects in 144 patients operated for facial paralysis, myringoplasty, stapedotomy, middle ear exploration for sudden hearing loss, and so forth, other than chronic suppurative otitis media with or without cholesteatoma, middle ear tumors, and anomaly. Correlation of intraoperative findings with preoperative computerized tomography was also analyzed in 35 patients. Conclusively, one out of every 10 surgical cases may have dehiscence of the facial canal which has to be always borne in mind during surgical manipulation of the middle ear. Computerized tomography has some limitations to evaluate the dehiscent facial canal due to high false negative and positive rates.

  13. Does facial resemblance enhance cooperation?

    Directory of Open Access Journals (Sweden)

    Trang Giang

    Full Text Available Facial self-resemblance has been proposed to serve as a kinship cue that facilitates cooperation between kin. In the present study, facial resemblance was manipulated by morphing stimulus faces with the participants' own faces or control faces (resulting in self-resemblant or other-resemblant composite faces. A norming study showed that the perceived degree of kinship was higher for the participants and the self-resemblant composite faces than for actual first-degree relatives. Effects of facial self-resemblance on trust and cooperation were tested in a paradigm that has proven to be sensitive to facial trustworthiness, facial likability, and facial expression. First, participants played a cooperation game in which the composite faces were shown. Then, likability ratings were assessed. In a source memory test, participants were required to identify old and new faces, and were asked to remember whether the faces belonged to cooperators or cheaters in the cooperation game. Old-new recognition was enhanced for self-resemblant faces in comparison to other-resemblant faces. However, facial self-resemblance had no effects on the degree of cooperation in the cooperation game, on the emotional evaluation of the faces as reflected in the likability judgments, and on the expectation that a face belonged to a cooperator rather than to a cheater. Therefore, the present results are clearly inconsistent with the assumption of an evolved kin recognition module built into the human face recognition system.

    Full Text Available Objective techniques to evaluate a facial movement are indispensable for the contemporary treatment of patients with motor disorders such as facial paralysis, cleft lip, postoperative head and neck cancer, and so on. Recently, computer-assisted, video-based techniques have been devised and reported as measuring systems in which facial movements can be evaluated quantitatively. Commercially available motion analysis systems, in which a stereo-measuring technique with multiple cameras and markers to facilitate search of matching among images through all cameras, also are utilized, and are used in many measuring systems such as video-based systems. The key is how the problems of facial movement can be extracted precisely, and how useful information for the diagnosis and decision-making process can be derived from analyses of facial movement. Therefore, it is important to discuss which facial animations should be examined, and whether fixation of the head and markers attached to the face can hamper natural facial movement.

    @@ Case History Ms. Zheng from Singapore, aged 51 years, paid her first visit on Aug.30, 2006, with the chief complaint of left facial paralysis accompanied with facial spasm for 5 years. The patient got left facial paralysis in 2001, which was not completely cured, and developed into facial spasm one year later. Although she had received various treatments including surgical operation, the disease was not cured. At the moment she had discomfort and dull sensation in the left facial area, mainly accompanied with twitching of the peripheral nerve of the eye. She was also accompanied with posterior auricular muscle tension and discomfort. She had fairly good sleep and appetite, but slightly quick temper. Physical examination at the moment showed that the patient had a slightly thin body figure, flushing face, and good mental state. The blood pressure was 110/75mmHg and the heart rate was 85 beats/min. No abnormal signs were found in the heart and lungs. The facial examination showed mild swelling of the left side of the face, incomplete closing of the eye lids, disappearance of wrinkles on the forehead, shallow nasolabial groove, and obvious muscle tension and tenderness in the left opisthotic region. Careful observation could find slight facial muscular twitching. The tongue proper was red with little coating, and the pulse thready-wiry.

    Full Text Available Facial melanoses (FM are a common presentation in Indian patients, causing cosmetic disfigurement with considerable psychological impact. Some of the well defined causes of FM include melasma, Riehl′s melanosis, Lichen planus pigmentosus, erythema dyschromicum perstans (EDP, erythrosis, and poikiloderma of Civatte. But there is considerable overlap in features amongst the clinical entities. Etiology in most of the causes is unknown, but some factors such as UV radiation in melasma, exposure to chemicals in EDP, exposure to allergens in Riehl′s melanosis are implicated. Diagnosis is generally based on clinical features. The treatment of FM includes removal of aggravating factors, vigorous photoprotection, and some form of active pigment reduction either with topical agents or physical modes of treatment. Topical agents include hydroquinone (HQ, which is the most commonly used agent, often in combination with retinoic acid, corticosteroids, azelaic acid, kojic acid, and glycolic acid. Chemical peels are important modalities of physical therapy, other forms include lasers and dermabrasion.

    2016-09-01

    Wrinkles are just one indicator of facial aging, but an indicator that is of prime importance in our world of facial aesthetics. Wrinkles occur where fault lines develop in aging skin. Those fault lines may be due to skin distortion resulting from facial expression or may be due to skin distortion from mechanical compression during sleep. Expression wrinkles and sleep wrinkles differ in etiology, location, and anatomical pattern. Compression, shear, and stress forces act on the face in lateral or prone sleep positions. We review the literature relating to the development of wrinkles and the biomechanical changes that occur in response to intrinsic and extrinsic influences. We explore the possibility that compression during sleep not only results in wrinkles but may also contribute to facial skin expansion.

    Full Text Available La parálisis facial afecta la musculatura de la mímica facial, generando alteraciones estéticas, funcionales y psicosociales. El manejo multidisciplinario es clave para lograr los mejores resultados, especialmente como apoyo a la cirugía reconstructiva. La estrategia de tratamiento está basada en un enfrentamiento sistemático de acuerdo a las características semiológicas y electromiográficas de cada paciente, lo que permite agruparlos de acuerdo a la reversibilidad y severidad de su patología. Los métodos de reconstrucción quirúrgica pueden ser estáticos o dinámicos (injerto cruzado de nervio sural, colgajo muscular libre con injerto de nervio sural ipsilateral o cruzado y colgajo mini-temporal. Incorporar la terapia física dentro del protocolo quirúrgico puede lograr mayor activación muscular, mayor simetría facial y reducir molestias postoperatorias como el edema facial, manejo de cicatrices, entre otros. Aunque existe reconocimiento sobre el impacto que posee el tratamiento de la parálisis facial, no existe a la fecha amplio consenso sobre cuál es el óptimo manejo de esta condición, y a pesar de los avances reportados durante los últimos años y la cantidad de técnicas propuestas en la literatura, la reanimación facial sigue siendo un desafío en cirugía reparadora.

  6. Pediatric facial burns: Is facial transplantation the new reconstructive psychosurgery?

    2008-01-01

    INTRODUCTION: Current pediatric burn care has resulted in survival being the expectation for most children. Composite tissue allotransplantation in the form of face or hand transplantation may present opportunities for reconstructive surgery of patients with burns. The present paper addresses the question “Could facial transplantation be of therapeutic benefit in the treatment of pediatric burns associated with facial disfigurement?” METHODS: Therapeutic benefit of facial transplantation was defined in terms of psychiatric adjustment and quality of life (QOL). To ascertain therapeutic benefit, studies of pediatric burn injury and associated psychiatric adjustment and QOL in children, adolescents and adults with pediatric burns, were reviewed. RESULTS: Pediatric burn injury is associated with anxiety disorders, including post-traumatic stress disorder and depressive disorders. Many patients with pediatric burns do not routinely access psychiatric care for these disorders, including those for psychiatric assessment of suicidal risk. A range of QOL outcomes were reported; four were predominantly satisfactory and one was predominantly unsatisfactory. DISCUSSION: Facial transplantation may reduce the risk of depressive and anxiety disorders other than post-traumatic stress disorder. Facial transplantation promises to be the new reconstructive psychosurgery, because it may be a surgical intervention with the potential to reduce the psychiatric suffering associated with pediatric burns. Furthermore, patients with pediatric burns may experience the stigma of disfigurement and psychiatric conditions. The potential for improved appearance with facial transplantation may reduce this ‘dual stigmata’. Studies combining surgical and psychiatric research are warranted. PMID:19949498

    Facial nerve palsy is a condition with several implications, particularly when occurring in childhood. It represents a serious clinical problem as it causes significant concerns in doctors because of its etiology, its treatment options and its outcome, as well as in little patients and their parents, because of functional and aesthetic outcomes. There are several described causes of facial nerve paralysis in children, as it can be congenital (due to delivery traumas and genetic or malformative diseases) or acquired (due to infective, inflammatory, neoplastic, traumatic or iatrogenic causes). Nonetheless, in approximately 40%-75% of the cases, the cause of unilateral facial paralysis still remains idiopathic. A careful diagnostic workout and differential diagnosis are particularly recommended in case of pediatric facial nerve palsy, in order to establish the most appropriate treatment, as the therapeutic approach differs in relation to the etiology.

    Full Text Available Change in a speaker’s emotion is a fundamental component in human communication. Automatic recognition of spontaneous emotion would significantly impact human-computer interaction and emotion-related studies in education, psychology and psychiatry. In this paper, we explore methods for detecting emotional facial expressions occurring in a realistic human conversation setting—the Adult Attachment Interview (AAI. Because non-emotional facial expressions have no distinct description and are expensive to model, we treat emotional facial expression detection as a one- class classification problem, which is to describe target objects (i.e., emotional facial expressions and distinguish them from outliers (i.e., non-emotional ones. Our preliminary experiments on AAI data suggest that one-class classification methods can reach a good balance between cost (labeling and computing and recognition performance by avoiding non-emotional expression labeling and modeling.

    The facial nerve is responsible for the motor innervation of the face. It has a visceral motor function (lacrimal, submandibular, sublingual glands and secretion of the nose); it conveys a great part of the taste fibers, participates to the general sensory of the auricle (skin of the concha) and the wall of the external auditory meatus. The facial mimic, production of tears, nasal flow and salivation all depend on the facial nerve. In order to image the facial nerve it is mandatory to be knowledgeable about its normal anatomy including the course of its efferent and afferent fibers and about relevant technical considerations regarding CT and MR to be able to achieve high-resolution images of the nerve.

    Background: Facial injuries in children always present a challenge in respect of their diagnosis and management. Since these children are of a growing age every care should be taken so that later the overall growth pattern of the facial skeleton in these children is not jeopardized. Purpose: To access the most feasible method for the management of facial injuries in children without hampering the facial growth. Materials and Methods: Sixty child patients with facial trauma were selected randomly for this study. On the basis of examination and investigations a suitable management approach involving rest and observation, open or closed reduction and immobilization, trans-osseous (TO) wiring, mini bone plate fixation, splinting and replantation, elevation and fixation of zygoma, etc. were carried out. Results and Conclusion: In our study fall was the predominant cause for most of the facial injuries in children. There was a 1.09% incidence of facial injuries in children up to 16 years of age amongst the total patients. The age-wise distribution of the fracture amongst groups (I, II and III) was found to be 26.67%, 51.67% and 21.67% respectively. Male to female patient ratio was 3:1. The majority of the cases of facial injuries were seen in Group II patients (6-11 years) i.e. 51.67%. The mandibular fracture was found to be the most common fracture (0.60%) followed by dentoalveolar (0.27%), mandibular + midface (0.07) and midface (0.02%) fractures. Most of the mandibular fractures were found in the parasymphysis region. Simple fracture seems to be commonest in the mandible. Most of the mandibular and midface fractures in children were amenable to conservative therapies except a few which required surgical intervention. PMID:22639504

    The purpose of this study is to clarify the confusing nomenclature and pathogenesis of Developmental Facial Paralysis, and how it can be differentiated from other causes of facial paralysis present at birth. Differentiating developmental from traumatic facial paralysis noted at birth is important for determining prognosis, but also for medicolegal reasons. Given the dramatic presentation of this condition, accurate and reliable guidelines are necessary in order to facilitate early diagnosis and initiate appropriate therapy, while providing support and counselling to the family. The 30 years experience of our center in the management of developmental facial paralysis is dependent upon a thorough understanding of facial nerve embryology, anatomy, nerve physiology, and an appreciation of well-recognized mishaps during fetal development. It is hoped that a better understanding of this condition will in the future lead to early targeted screening, accurate diagnosis and prompt treatment in this population of facially disfigured patients, which will facilitate their emotional and social rehabilitation, and their reintegration among their peers.

    Aesthetic units of the face can be divided into facial content (FC; eyes, nose, lips, and mouth), anterior facial frame (AFF; a contour line from the trichion, the temporal line of the frontal bone, the lateral orbital rim, the most lateral line of the anterior part of the zygomatic body, the anterior border of the masseter muscle, to the inferior border of the chin), and posterior facial frame (PFF; a contour line from the hairline, the zygomatic arch, to the ramus and gonial angle area of the mandible). The size and shape of each FC and the balance and proportion between FCs create a unique appearance for each person. The facial form can be determined through the combination of AFF and PFF. In the Asian population, clinicians frequently encounter problems of FC (eg, acute nasolabial angle, protrusive and everted lips, nonconsonant lip line, or lip canting), AFF (eg, midface hypoplasia, protrusive and asymmetric chin, vertical deficiency/excess of the anterior maxilla and symphysis, or prominent zygoma), and PFF (eg, square mandibular angle). These problems can be efficiently and effectively corrected through the combination of hard tissue surgery such as anterior segmental osteotomy, genioplasty, mandibular angle reduction, malarplasty, and orthognathic surgery. Therefore, the purposes of this article were to introduce the concepts of FC, AFF, and PFF, and to explain the effects of facial hard tissue surgery on facial aesthetics.

    2015-01-01

    The management of acute facial nerve insult may entail medical therapy, surgical exploration, decompression, or repair depending on the etiology. When recovery is not complete, facial mimetic function lies on a spectrum ranging from flaccid paralysis to hyperkinesis resulting in facial immobility. Through systematic assessment of the face at rest and with movement, one may tailor the management to the particular pattern of dysfunction. Interventions for long-standing facial palsy include physical therapy, injectables, and surgical reanimation procedures. The goal of the management is to restore facial balance and movement. This article summarizes a contemporary approach to the management of facial nerve insults.

    Full Text Available The current study addressed whether rated femininity, attractiveness, and health in female faces are associated with numerous indices of self-reported health history (number of colds/stomach bugs/frequency of antibiotic use in a sample of 105 females. It was predicted that all three rating variables would correlate negatively with bouts of illness (with the exception of rates of stomach infections, on the assumption that aspects of facial appearance signal mate quality. The results showed partial support for this prediction, in that there was a general trend for both facial femininity and attractiveness to correlate negatively with the reported number of colds in the preceding twelve months and with the frequency of antibiotic use in the last three years and the last twelve months. Rated facial femininity (as documented in September was also associated with days of flu experienced in the period spanning the November-December months. However, rated health did not correlate with any of the health indices (albeit one marginal result with antibiotic use in the last twelve months. The results lend support to previous findings linking facial femininity to health and suggest that facial femininity may be linked to some aspects of disease resistance but not others.

  14. Cortical control of facial expression.

    Müri, René M

    2016-06-01

    The present Review deals with the motor control of facial expressions in humans. Facial expressions are a central part of human communication. Emotional face expressions have a crucial role in human nonverbal behavior, allowing a rapid transfer of information between individuals. Facial expressions can be either voluntarily or emotionally controlled. Recent studies in nonhuman primates and humans have revealed that the motor control of facial expressions has a distributed neural representation. At least five cortical regions on the medial and lateral aspects of each hemisphere are involved: the primary motor cortex, the ventral lateral premotor cortex, the supplementary motor area on the medial wall, and the rostral and caudal cingulate cortex. The results of studies in humans and nonhuman primates suggest that the innervation of the face is bilaterally controlled for the upper part and mainly contralaterally controlled for the lower part. Furthermore, the primary motor cortex, the ventral lateral premotor cortex, and the supplementary motor area are essential for the voluntary control of facial expressions. In contrast, the cingulate cortical areas are important for emotional expression, because they receive input from different structures of the limbic system.

    Peripheral facial weakness is a facial nerve damage that results in muscle weakness on one side of the face. It may be idiopathic (Bell's palsy) or may have a detectable cause. Almost 80% of peripheral facial weakness cases are primary and the rest of them are secondary. The most frequent causes of secondary peripheral facial weakness are systemic viral infections, trauma, surgery, diabetes, local infections, tumor, immune disorders, drugs, degenerative diseases of the central nervous system, etc. The diagnosis relies upon the presence of typical signs and symptoms, blood chemistry tests, cerebrospinal fluid investigations, nerve conduction studies and neuroimaging methods (cerebral MRI, x-ray of the skull and mastoid). Treatment of secondary peripheral facial weakness is based on therapy for the underlying disorder, unlike the treatment of Bell's palsy that is controversial due to the lack of large, randomized, controlled, prospective studies. There are some indications that steroids or antiviral agents are beneficial but there are also studies that show no beneficial effect. Additional treatments include eye protection, physiotherapy, acupuncture, botulinum toxin, or surgery. Bell's palsy has a benign prognosis with complete recovery in about 80% of patients, 15% experience some mode of permanent nerve damage and severe consequences remain in 5% of patients.

  16. Compound facial expressions of emotion.

    2014-04-15

    Understanding the different categories of facial expressions of emotion regularly used by us is essential to gain insights into human cognition and affect as well as for the design of computational models and perceptual interfaces. Past research on facial expressions of emotion has focused on the study of six basic categories--happiness, surprise, anger, sadness, fear, and disgust. However, many more facial expressions of emotion exist and are used regularly by humans. This paper describes an important group of expressions, which we call compound emotion categories. Compound emotions are those that can be constructed by combining basic component categories to create new ones. For instance, happily surprised and angrily surprised are two distinct compound emotion categories. The present work defines 21 distinct emotion categories. Sample images of their facial expressions were collected from 230 human subjects. A Facial Action Coding System analysis shows the production of these 21 categories is different but consistent with the subordinate categories they represent (e.g., a happily surprised expression combines muscle movements observed in happiness and surprised). We show that these differences are sufficient to distinguish between the 21 defined categories. We then use a computational model of face perception to demonstrate that most of these categories are also visually discriminable from one another.

  17. [The history of facial paralysis].

    Facial paralysis has been a recognized condition since Antiquity, and was mentionned by Hippocratus. In the 17th century, in 1687, the Dutch physician Stalpart Van der Wiel rendered a detailed observation. It was, however, Charles Bell who, in 1821, provided the description that specified the role of the facial nerve. Facial nerve surgery began at the end of the 19th century. Three different techniques were used successively: nerve anastomosis, (XI-VII Balance 1895, XII-VII, Korte 1903), myoplasties (Lexer 1908), and suspensions (Stein 1913). Bunnell successfully accomplished the first direct facial nerve repair in the temporal bone, in 1927, and in 1932 Balance and Duel experimented with nerve grafts. Thanks to progress in microsurgical techniques, the first faciofacial anastomosis was realized in 1970 (Smith, Scaramella), and an account of the first microneurovascular muscle transfer published in 1976 by Harii. Treatment of the eyelid paralysis was at the origin of numerous operations beginning in the 1960s; including palpebral spring (Morel Fatio 1962) silicone sling (Arion 1972), upperlid loading with gold plate (Illig 1968), magnets (Muhlbauer 1973) and transfacial nerve grafts (Anderl 1973). By the end of the 20th century, surgeons had at their disposal a wide range of valid techniques for facial nerve surgery, including modernized versions of older techniques.

    Facial paralysis represents the end result of a wide array of disorders and heterogeneous etiologies, including congenital, traumatic, infectious, neoplastic, and metabolic causes. Thus, facial palsy has a diverse range of presentations, from transient unilateral paresis to devastating permanent bilateral paralysis. Although not life-threatening, facial paralysis remains relatively common and can have truly severe effects on one's quality of life, with important ramifications in terms of psychological impact and physiologic burden. Prognosis and outcomes for patients with facial paralysis are highly dependent on the etiologic nature of the weakness as well as the treatment offered to the patient. Facial plastic surgeons are often asked to manage the sequelae of long-standing facial paralysis. It is important, however, for any practitioner who assists this population to have a sophisticated understanding of the common etiologies and initial management of facial paralysis. This article reviews the more common causes of facial paralysis and discusses relevant early treatment strategies.

  2. [Therapy for atypical facial pain].

    Science.gov (United States)

    Ishida, Satoshi; Kimura, Hiroko

    2009-09-01

    Atypical facial pain is a pain in the head, neck and the face, without organic causes. It is treated at departments of physical medicine, such as dental, oral and maxillofacial surgery, otolaryngology, cerebral surgery, or head and neck surgery. In primary care, it is considered to be a medically unexplained symptom (MUS), or a somatoform disorder, such as somatization caused by a functional somatic syndrome (FSS) by psychiatrists. Usually, patients consult departments of physical medicine complaining of physical pain. Therefore physicians in these departments should examine the patients from the holistic perspective, and identify organic diseases. As atypical facial pain becomes chronic, other complications, including psychiatric complaints other than physical pain, such as depression may develop. Moreover, physical, psychological, and social factors affect the symptoms by interacting with one another. Therefore, in examining atypical facial pain, doctors specializing in dental, oral and maxillofacial medicine are required to provide psychosomatic treatment that is based on integrated knowledge.

    2005-11-22

    It has been hypothesized that the social dysfunction in social developmental disorders (SDDs), such as autism, Asperger disorder, and the socioemotional processing disorder, impairs the acquisition of normal face-processing skills. The authors investigated whether this purported perceptual deficit was generalized to both facial expression and facial identity or whether these different types of facial perception were dissociated in SDDs. They studied 26 adults with a variety of SDD diagnoses, assessing their ability to discriminate famous from anonymous faces, their perception of emotional expression from facial and nonfacial cues, and the relationship between these abilities. They also compared the performance of two defined subgroups of subjects with SDDs on expression analysis: one with normal and one with impaired recognition of facial identity. While perception of facial expression was related to the perception of nonfacial expression, the perception of facial identity was not related to either facial or nonfacial expression. Likewise, subjects with SDDs with impaired facial identity processing perceived facial expression as well as those with normal facial identity processing. The processing of facial identity and that of facial expression are dissociable in social developmental disorders. Deficits in perceiving facial expression may be related to emotional processing more than face processing. Dissociations between the perception of facial identity and facial emotion are consistent with current cognitive models of face processing. The results argue against hypotheses that the social dysfunction in social developmental disorder causes a generalized failure to acquire face-processing skills.

    Full Text Available BACKGROUND Facial hypermelanosis is a clinical feature of a diverse group of disorders most commonly in middle-aged females who are exposed to sunlight. There is a considerable overlap in clinical features among the clinical entities of facial hypermelanosis. Aetiology in most of facial melanosis is unknown, but some factors like UV radiation in melasma and exposure to allergens in Riehl’s melanosis could be implicated. Histopathology is an accurate diagnostic tool. The benefit of histopathology is not only to confirm diagnosis, but also to exclude related disorders. Among the hyperpigmented conditions, melasma, Riehl’s melanosis, Acanthosis Nigricans (AN and Lichen Planus Pigmentosus (LPP are the common causes of facial hypermelanosis - most common being melasma. MATERIALS AND METHODS This is a descriptive cross-sectional study of hundred consenting patients who attended the outpatient wing of Dermatology Department of Government Medical College, Kottayam. They were included only after getting the written informed consent. RESULTS Maximum number of patients were in the 5 th decade. 65% were females. Homemakers/housewives constituted the main study group (34%.55% of patients had duration of pigmentation between 1 to 5 years. Among these, melasma and acanthosis nigricans had the longest duration of disease. 69% of patients were symptomatic. Most common clinical diagnosis was melasma (45 followed by acanthosis nigricans (17, Riehl’s melanosis (15 and lichen planus pigmentosus (14.

    Facial skin care products and cosmetics can both aid or incite facial dermatoses. Properly selected skin care can create an environment for barrier repair aiding in the re-establishment of a healing biofilm and diminution of facial redness; however, skin care products that aggressively remove intercellular lipids or cause irritation must be eliminated before the red face will resolve. Cosmetics are an additive variable either aiding or challenging facial skin health.

    Full Text Available The purpose of this classification of facial aging is to have a simple clinical method to determine the severity of the aging process in the face. This allows a quick estimate as to the types of procedures that the patient would need to have the best results. Procedures that are presently used for facial rejuvenation include laser, chemical peels, suture lifts, fillers, modified facelift and full facelift. The physician is already using his best judgment to determine which procedure would be best for any particular patient. This classification may help to refine these decisions.

    Darwin did not focus on deception. Only a few sentences in his book mentioned the issue. One of them raised the very interesting question of whether it is difficult to voluntarily inhibit the emotional expressions that are most difficult to voluntarily fabricate. Another suggestion was that it would be possible to unmask a fabricated expression by the absence of the difficult-to-voluntarily-generate facial actions. Still another was that during emotion body movements could be more easily suppressed than facial expression. Research relevant to each of Darwin's suggestions is reviewed, as is other research on deception that Darwin did not foresee.

  11. Connections between the facial and trigeminal nerves: Anatomical basis for facial muscle proprioception

    Directory of Open Access Journals (Sweden)

    J.L. Cobo

    2017-06-01

    Full Text Available Proprioception is a quality of sensibility that originates in specialized sensory organs (proprioceptors that inform the central nervous system about static and dynamic conditions of muscles and joints. The facial muscles are innervated by efferent motor nerve fibers and typically lack proprioceptors. However, facial proprioception plays a key role in the regulation and coordination of the facial musculature and diverse reflexes. Thus, facial muscles must be necessarily supplied also for afferent sensory nerve fibers provided by other cranial nerves, especially the trigeminal nerve. Importantly, neuroanatomical studies have demonstrated that facial proprioceptive impulses are conveyed through branches of the trigeminal nerve to the central nervous system. The multiple communications between the facial and the trigeminal nerves are at the basis of these functional characteristics. Here we review the literature regarding the facial (superficial communications between the facial and the trigeminal nerves, update the current knowledge about proprioception in the facial muscles, and hypothesize future research in facial proprioception.

    Full Text Available Dentro de la antropología y la identificación forense, la aproximación facial (también conocida como "reconstrucción facial" se presenta frecuentemente como un hecho consumado, con evidencia mínima de las investigaciones y los métodos usados para alcanzar los resultados. Este trabajo presenta un panorama detallado de la investigación y los métodos usados para realizar una aproximación facial grafica en 2D de un hombre prehistórico del valle de Jachal, provincia de San Juan, Argentina. Se entiende que corresponde a un miembro del extinto grupo Huarpe. El cráneo del individuo muestra numerosos rasgos morfológicos que son consistentes con lo que se conoce acerca de este grupo de agricultores tempranos americanos. Debido a que muchos de los métodos utilizados en esta reconstrucción facial aun no han sido verificados y aquellos que han sido debidamente probados se basan en promedios estadísticos de la variación humana, los resultados presentados deben ser vistos como indicativos de la posible apariencia facial del individuo dado el nivel actual de conocimiento, más que como un resultado definitivo.

    1996-01-01

    Three-dimensional facial morphometry was investigated in a sample of 40 men and 40 women, with a new noninvasive computerized method. Subjects ranged in age between 19 and 32 years, had sound dentitions, and no craniocervical disorders. For each subject, 16 cutaneous facial landmarks were automatically collected by a system consisting of two infrared camera coupled device (CCD) cameras, real time hardware for the recognition of markers, and software for the three-dimensional reconstruction of landmarks' x, y, z coordinates. From these landmarks, 15 linear and 10 angular measurements, and four linear distance ratios were computed and averaged for sex. For all angular values, both samples showed a narrow variability and no significant gender differences were demonstrated. Conversely, all the linear measurements were significantly higher in men than in women. The highest intersample variability was observed for the measurements of facial height (prevalent vertical dimension), and the lowest for the measurements of facial depth (prevalent horizontal dimension). The proportions of upper and lower face height relative to the anterior face height showed a significant sex difference. Mean values were in good agreement with literature data collected with traditional methods. The described method allowed the direct and noninvasive calculation of three-dimensional linear and angular measurements that would be usefully applied in clinics as a supplement to the classic x-ray cephalometric analyses.

  1. Topical management of facial burns.

    2008-11-01

    The face is the central point of the physical features of the human being. It transmits expressions and emotions, communicates feelings and allows for individual identity. It contains complex musculature and a pliable and unique skin envelope that reacts to the environment through a vast network of nerve endings. The face hosts vital areas that make phonation, feeding, and vision possible. Facial burns disrupt these anatomical and functional structures creating pain, deformity, swelling, and contractures that may lead to lasting physical and psychological sequelae. The management of facial burns may include operative and non-operative treatment or both, depending on the depth and extent of the burn. This paper intends to provide a review of the available options for topical management of facial burns. Topical agents will be defined as any agent applied to the surface of the skin that alters the outcome of the facial burn. Therefore, the classic concept of topical therapy will be expanded and developed within two major stages: acute and rehabilitation. Comparison of the effectiveness of the different treatments and relevant literature will be discussed.

    2012-07-01

    To discuss the neurological basis of facial recognition, we present our case reports of impaired recognition and a review of previous literature. First, we present a case of infarction and discuss prosopagnosia, which has had a large impact on face recognition research. From a study of patient symptoms, we assume that prosopagnosia may be caused by unilateral right occipitotemporal lesion and right cerebral dominance of facial recognition. Further, circumscribed lesion and degenerative disease may also cause progressive prosopagnosia. Apperceptive prosopagnosia is observed in patients with posterior cortical atrophy (PCA), pathologically considered as Alzheimer's disease, and associative prosopagnosia in frontotemporal lobar degeneration (FTLD). Second, we discuss face recognition as part of communication. Patients with Parkinson disease show social cognitive impairments, such as difficulty in facial expression recognition and deficits in theory of mind as detected by the reading the mind in the eyes test. Pathological and functional imaging studies indicate that social cognitive impairment in Parkinson disease is possibly related to damages in the amygdalae and surrounding limbic system. The social cognitive deficits can be observed in the early stages of Parkinson disease, and even in the prodromal stage, for example, patients with rapid eye movement (REM) sleep behavior disorder (RBD) show impairment in facial expression recognition. Further, patients with myotonic dystrophy type 1 (DM 1), which is a multisystem disease that mainly affects the muscles, show social cognitive impairment similar to that of Parkinson disease. Our previous study showed that facial expression recognition impairment of DM 1 patients is associated with lesion in the amygdalae and insulae. Our study results indicate that behaviors and personality traits in DM 1 patients, which are revealed by social cognitive impairment, are attributable to dysfunction of the limbic system.

    Full Text Available In this review, we introduced our three studies that focused on facial movements. In the first study, we examined the temporal characteristics of neural responses elicited by viewing mouth movements, and assessed differences between the responses to mouth opening and closing movements and an averting eyes condition. Our results showed that the occipitotemporal area, the human MT/V5 homologue, was active in the perception of both mouth and eye motions. Viewing mouth and eye movements did not elicit significantly different activity in the occipitotemporal area, which indicated that perception of the movement of facial parts may be processed in the same manner, and this is different from motion in general. In the second study, we investigated whether early activity in the occipitotemporal region evoked by eye movements was influenced by a face contour and/or features such as the mouth. Our results revealed specific information processing for eye movements in the occipitotemporal region, and this activity was significantly influenced by whether movements appeared with the facial contour and/or features, in other words, whether the eyes moved, even if the movement itself was the same. In the third study, we examined the effects of inverting the facial contour (hair and chin and features (eyes, nose, and mouth on processing for static and dynamic face perception. Our results showed the following: (1 In static face perception, activity in the right fusiform area was affected more by the inversion of features while that in the left fusiform area was affected more by a disruption in the spatial relationship between the contour and features, and (2 In dynamic face perception, activity in the right occipitotemporal area was affected by the inversion of the facial contour.

    2009-09-01

    Full Text Available Abstract Background Previous reports have suggested impairment in facial expression recognition in delinquents, but controversy remains with respect to how such recognition is impaired. To address this issue, we investigated facial expression recognition in delinquents in detail. Methods We tested 24 male adolescent/young adult delinquents incarcerated in correctional facilities. We compared their performances with those of 24 age- and gender-matched control participants. Using standard photographs of facial expressions illustrating six basic emotions, participants matched each emotional facial expression with an appropriate verbal label. Results Delinquents were less accurate in the recognition of facial expressions that conveyed disgust than were control participants. The delinquents misrecognized the facial expressions of disgust as anger more frequently than did controls. Conclusion These results suggest that one of the underpinnings of delinquency might be impaired recognition of emotional facial expressions, with a specific bias toward interpreting disgusted expressions as hostile angry expressions.

    Parotid lymphangioma is a relatively rare disease that is usually detected in infancy or early childhood, and which has typical features. Clinical reports of facial nerve paralysis caused by lymphangioma, however, are very rare. Usually, facial nerve paralysis in a child suggests malignancy. Here we report a very rare case of parotid lymphangioma associated with facial nerve paralysis. A 7-year-old boy was admitted to hospital with a rapidly enlarging mass in the left parotid region. Left peripheral-type facial nerve paralysis was also noted. Computed tomography and magnetic resonance imaging also revealed multiple cystic lesions. Open biopsy was undertaken in order to investigate the cause of the facial nerve paralysis. The histopathological findings of the excised tumor were consistent with lymphangioma. Prednisone (40 mg/day) was given in a tapering dose schedule. Facial nerve paralysis was completely cured 1 month after treatment. There has been no recurrent facial nerve paralysis for eight years.

    For realizing the flexible man-machine collaboration, understanding of facial expressions and gestures is not negligible. In our method, we proposed a hierarchical recognition approach, for the understanding of human emotions. According to this method, the facial AFs (action features) were firstly extracted and recognized by using histograms of optical flow. Then, based on the facial AFs, facial expressions were classified into two calsses, one of which presents the positive emotions, and the other of which does the negative ones. Accordingly, the facial expressions belonged to the positive class, or the ones belonged to the negative class, were classified into more complex emotions, which were revealed by the corresponding facial expressions. Finally, the system architecture how to coordinate in recognizing facil action features and facial expressions for man-machine collaboration was proposed.

    CLAUDIA QUINTERO

    2015-01-01

    Full Text Available Los endofenotipos son rasgos presentes antes de la aparición de un trastorno y podrían ser útiles para identificar genes de susceptibilidad. Se determinó si personas con esquizofrenia y sus familiares de primer grado no afectados tenían un desempeño menor que los controles en la Tarea de Multitransformación de Expresión Emocional, que mide reconocimiento de emociones faciales. Las personas con esquizofrenia y sus familiares mostraron menor sensibilidad o requirieron más intensidad para identificar emociones que los controles. La exactitud para identificar emociones fue similar entre familiares y controles, pero menor en aquellos con esquizofrenia. Esto sugiere que la sensibilidad para el reconocimiento de emociones faciales es un endofenotipo de la esquizofrenia.

    For women, choosing a facially masculine man as a mate is thought to confer genetic benefits to offspring. Crucial assumptions of this hypothesis have not been adequately tested. It has been assumed that variation in facial masculinity is due to genetic variation and that genetic factors that increase male facial masculinity do not increase facial masculinity in female relatives. We objectively quantified the facial masculinity in photos of identical (n = 411) and nonidentical (n = 782) twins and their siblings (n = 106). Using biometrical modeling, we found that much of the variation in male and female facial masculinity is genetic. However, we also found that masculinity of male faces is unrelated to their attractiveness and that facially masculine men tend to have facially masculine, less-attractive sisters. These findings challenge the idea that facially masculine men provide net genetic benefits to offspring and call into question this popular theoretical framework.

  16. Facial Expression at Retrieval Affects Recognition of Facial Identity

    Directory of Open Access Journals (Sweden)

    Wenfeng eChen

    2015-06-01

    Full Text Available It is well known that memory can be modulated by emotional stimuli at the time of encoding and consolidation. For example, happy faces create better identity recognition than faces with certain other expressions. However, the influence of facial expression at the time of retrieval remains unknown in the literature. To separate the potential influence of expression at retrieval from its effects at earlier stages, we had participants learn neutral faces but manipulated facial expression at the time of memory retrieval in a standard old/new recognition task. The results showed a clear effect of facial expression, where happy test faces were identified more successfully than angry test faces. This effect is unlikely due to greater image similarity between the neutral learning face and the happy test face, because image analysis showed that the happy test faces are in fact less similar to the neutral learning faces relative to the angry test faces. In the second experiment, we investigated whether this emotional effect is influenced by the expression at the time of learning. We employed angry or happy faces as learning stimuli, and angry, happy, and neutral faces as test stimuli. The results showed that the emotional effect at retrieval is robust across different encoding conditions with happy or angry expressions. These findings indicate that emotional expressions affect the retrieval process in identity recognition, and identity recognition does not rely on emotional association between learning and test faces.

    Karate is a martial art that carries a high trauma risk. Trauma-related Swiss and European karate data are currently unavailable. This survey seeks to increase knowledge of the incidence of traumatic facial and dental injuries, their emergency management, awareness of tooth rescue boxes, the use of mouthguards and their modifications. Interviews were conducted with 420 karate fighters from 43 European countries using a standardized questionnaire. All the participants were semi-professionals. The data were evaluated with respect to gender, kumite level (where a karate practitioner trains against an adversary), and country. Of the 420 fighters interviewed, 213 had experienced facial trauma and 44 had already had dental trauma. A total of 192 athletes had hurt their opponent by inflicting a facial or dental injury, and 290 knew about the possibility of tooth replantation following an avulsion. Only 50 interviewees knew about tooth rescue boxes. Nearly all the individuals interviewed wore a mouthguard (n = 412), and 178 of them had made their own modifications to the guard. The results of the present survey suggest that more information and education in wearing protective gear are required to reduce the incidence of dental injuries in karate.

  18. Recognizing Action Units for Facial Expression Analysis.

    Tian, Ying-Li; Kanade, Takeo; Cohn, Jeffrey F

    2001-02-01

    Most automatic expression analysis systems attempt to recognize a small set of prototypic expressions, such as happiness, anger, surprise, and fear. Such prototypic expressions, however, occur rather infrequently. Human emotions and intentions are more often communicated by changes in one or a few discrete facial features. In this paper, we develop an Automatic Face Analysis (AFA) system to analyze facial expressions based on both permanent facial features (brows, eyes, mouth) and transient facial features (deepening of facial furrows) in a nearly frontal-view face image sequence. The AFA system recognizes fine-grained changes in facial expression into action units (AUs) of the Facial Action Coding System (FACS), instead of a few prototypic expressions. Multistate face and facial component models are proposed for tracking and modeling the various facial features, including lips, eyes, brows, cheeks, and furrows. During tracking, detailed parametric descriptions of the facial features are extracted. With these parameters as the inputs, a group of action units (neutral expression, six upper face AUs and 10 lower face AUs) are recognized whether they occur alone or in combinations. The system has achieved average recognition rates of 96.4 percent (95.4 percent if neutral expressions are excluded) for upper face AUs and 96.7 percent (95.6 percent with neutral expressions excluded) for lower face AUs. The generalizability of the system has been tested by using independent image databases collected and FACS-coded for ground-truth by different research teams.

    Shapiro, J; Lui, H

    Twenty-two percent of women in North America have unwanted facial hair, which can cause embarrassment and result in a significant emotional burden. Treatment options include plucking, waxing (including the sugar forms), depilatories, bleaching, shaving, electrolysis, laser, intense pulsed light (IPL), and eflornithine 13.9% cream (Vaniqa, Barrier Therapeutics in Canada and Shire Pharmaceuticals elsewhere). Eflornithine 13.9% cream is a topical treatment that does not remove the hairs, but acts to reduce the rate of growth and appears to be effective for unwanted facial hair on the mustache and chin area. Eflornithine 13.9% cream can be used in combination with other treatments such as lasers and IPL to give the patient the best chance for successful hair removal.

    2012-07-01

    Lymphangiomas are uncommon congenital malformations of the lymphatic system, generally diagnosed during childhood. These malformations are rarely seen in adults, and the literature provides poor guidelines for treatment options that must be carefully applied to the facial region. Diagnosis in adult subjects is difficult to achieve, and also management of these conditions is still challenging because they tend to infiltrate adjacent tissues, causing frequent relapses. Radical surgery is the main form of treatment, avoiding the sacrifice of function or aesthetics of the patient. Two cases of cystic lymphangioma of the facial region found in adults are described from a clinical and pathologic point of view. The aim of this article was to point out that an early recognition of cystic lymphangioma is a crucial goal to initiate a prompt treatment avoiding serious complication.

    The ability of patients with unilateral facial paralysis to recognize and appropriately judge facial expressions remains underexplored. To test the effects of unilateral facial paralysis on the recognition of and judgments about facial expressions of emotion and to evaluate the asymmetry of facial mimicry. Patients with left or right unilateral facial paralysis at a university facial plastic surgery unit completed 2 computer tasks involving video facial expression recognition. Side of facial paralysis was used as a between-participant factor. Facial function and symmetry were verified electronically with the eFACE facial function scale. Across 2 tasks, short videos were shown on which facial expressions of happiness and anger unfolded earlier on one side of the face or morphed into each other. Patients indicated the moment or side of change between facial expressions and judged their authenticity. Type, time, and accuracy of responses on a keyboard were analyzed. A total of 57 participants (36 women and 21 men) aged 20 to 76 years (mean age, 50.2 years) and with mild left or right unilateral facial paralysis were included in the study. Patients with right facial paralysis were faster (by about 150 milliseconds) and more accurate (mean number of errors, 1.9 vs 2.5) to detect expression onsets on the left side of the stimulus face, suggesting anatomical asymmetry of facial mimicry. Patients with left paralysis, however, showed more anomalous responses, which partly differed by emotion. The findings favor the hypothesis of an anatomical asymmetry of facial mimicry and suggest that patients with a left hemiparalysis could be more at risk of developing a cluster of disabilities and psychological conditions including emotion-recognition impairments. 3.

  8. Removal of unwanted facial hair.

    2002-11-15

    Unwanted facial hair is a common problem that is seldom discussed in the primary care setting. Although men occasionally request removal of unwanted facial hair, women most often seek help with this condition. Physicians generally neglect to address the problem if the patient does not first request help. The condition may be caused by androgen overproduction, increased sensitivity to circulating androgens, or other metabolic and endocrine disorders, and should be properly evaluated. Options for hair removal vary in efficacy, degree of discomfort, and cost. Clinical studies on the efficacy of many therapies are lacking. Short of surgical removal of the hair follicle, the only permanent treatment is electrolysis. However, the practice of electrolysis lacks standardization, and regulation of the procedure varies from state to state. Shaving, epilation, and depilation are the most commonly attempted initial options for facial hair removal. Although these methods are less expensive, they are only temporary. Laser hair removal, although better studied than most methods and more strictly regulated, has yet to be proved permanent in all patients. Eflornithine, a topical treatment, is simple to apply and has minimal side effects. By the time most patients consult a physician, they have tried several methods of hair removal. Family physicians can properly educate patients and recommend treatment for this common condition if they are armed with basic knowledge about the treatment options.

  9. Identification based on facial parts

    Full Text Available Two opposing views dominate face identification literature, one suggesting that the face is processed as a whole and another suggesting analysis based on parts. Our research tried to establish which of these two is the dominant strategy and our results fell in the direction of analysis based on parts. The faces were covered with a mask and the participants were uncovering different parts, one at the time, in an attempt to identify a person. Already at the level of a single facial feature, such as mouth or eye and top of the nose, some observers were capable to establish the identity of a familiar face. Identification is exceptionally successful when a small assembly of facial parts is visible, such as eye, eyebrow and the top of the nose. Some facial parts are not very informative on their own but do enhance recognition when given as a part of such an assembly. Novel finding here is importance of the top of the nose for the face identification. Additionally observers have a preference toward the left side of the face. Typically subjects view the elements in the following order: left eye, left eyebrow, right eye, lips, region between the eyes, right eyebrow, region between the eyebrows, left check, right cheek. When observers are not in a position to see eyes, eyebrows or top of the nose, they go for lips first and then region between the eyebrows, region between the eyes, left check, right cheek and finally chin.

    Full Text Available Las quemaduras faciales constituyen un grupo dentro de las quemaduras consideradas como en zona especial dada las potenciales secuelas estéticas y funcionales que pueden resultar de su tratamiento, por este motivo, un adecuado manejo reducirá estos riesgos. La cara posee una rica irrigación de tal forma que el manejo deberá ser más conservador que en otras zonas del cuerpo. Las quemaduras superficiales requieren de un tratamiento basado en ungüentos antibióticos y cobertura con apósitos sintéticos transitorios en espera de epidermización. En quemaduras faciales profundas el tratamiento consistirá en escarectomía química y quirúrgica una vez definida la quemadura y su posterior cobertura con tejido autólogo o sustitutos dérmicos definitivos respetando las unidades estético-funcionales de la cara. Este grupo de quemadura luego de la primera atención deberá ser derivada a un centro de quemados para su manejo integral.

The respective 3D accuracy of stereophotography and structured light facial scanners obtained for facial deformities was 0.58±0.11 mm and 0.57±0.07 mm. The 3D accuracy of different facial partitions was inconsistent; the middle face had the best performance. Although the PA of two facial scanners was lower than their nominal accuracy (NA), they all met the requirement for oral clinic use.

    Full Text Available For the successful reconstruction of facial defects, various perforator flaps have been used in single-stage surgery, where tissues are moved to adjacent defect sites. Our group successfully performed perforator flap surgery on 17 patients with small to moderate facial defects that affected the functional and aesthetic features of their faces. Of four complicated cases, three developed venous congestion, which resolved in the subacute postoperative period, and one patient with partial necrosis underwent minor revision. We reviewed the literature on freestyle perforator flaps for facial defect reconstruction and focused on English articles published in the last five years. With the advance of knowledge regarding the vascular anatomy of pedicled perforator flaps in the face, we found that some perforator flaps can improve functional and aesthetic reconstruction for the facial defects. We suggest that freestyle facial perforator flaps can serve as alternative, safe, and versatile treatment modalities for covering small to moderate facial defects.

    Facial and tongue muscles are commonly involved in patients with neuromuscular disorders. However, these muscles are not as easily accessible for biopsy and pathological examination as limb muscles. We have previously investigated myasthenia gravis patients with MuSK antibodies for facial and tongue muscle atrophy using different magnetic resonance imaging sequences, including ultrashort echo time techniques and image analysis tools that allowed us to obtain quantitative assessments of facial muscles. This imaging study had shown that facial muscle measurement is possible and that useful information can be obtained using a quantitative approach. In this paper we aim to review in detail the methods that we applied to our study, to enable clinicians to study these muscles within the domain of neuromuscular disease, oncological or head and neck specialties. Quantitative assessment of the facial musculature may be of value in improving the understanding of pathological processes occurring within facial muscles in certain neuromuscular disorders.

    Facial clinical signs and their integration are the basis of perception than others could have from ourselves, noticeably the age they imagine we are. Facial modifications in motion and their objective measurements before and after application of skin regimen are essential to go further in evaluation capacities to describe efficacy in facial dynamics. Quantification of facial modifications vis à vis gravity will allow us to answer about 'control' of facial shape in daily activities. Standardized photographs of the faces of 30 Caucasian female subjects of various ages (24-73 year) were successively taken at upright and supine positions within a short time interval. All these pictures were therefore reframed - any bias due to facial features was avoided when evaluating one single sign - for clinical quotation by trained experts of several facial signs regarding published standardized photographic scales. For all subjects, the supine position increased facial width but not height, giving a more fuller appearance to the face. More importantly, the supine position changed the severity of facial ageing features (e.g. wrinkles) compared to an upright position and whether these features were attenuated or exacerbated depended on their facial location. Supine station mostly modifies signs of the lower half of the face whereas those of the upper half appear unchanged or slightly accentuated. These changes appear much more marked in the older groups, where some deep labial folds almost vanish. These alterations decreased the perceived ages of the subjects by an average of 3.8 years. Although preliminary, this study suggests that a 90° rotation of the facial skin vis à vis gravity induces rapid rearrangements among which changes in tensional forces within and across the face, motility of interstitial free water among underlying skin tissue and/or alterations of facial Langer lines, likely play a significant role. © 2015 Society of Cosmetic Scientists and the Société Fran

    We describe a male patient who presented a progressive conductive unilateral hearing loss 20 years after otosclerosis surgery. Computed tomography (CT) scan and magnetic resonance imaging (MRI) findings suggested a facial schwannoma in its tympanic segment. At the time of revision surgery, a facial schwannoma was found to originate at the tympanic segment, pushing the prosthesis out of the oval window fenestration. The Teflon-piston was repositioned with difficulties in the central platinotomy, and the facial schwannoma was left intact.

    Peripheral facial paresis is one of the most common diagnosed neuropathies in adults and also in children. Many factors can trigger facial paresis and most frequent are infectious, carcinoma and demyelinisation diseases. Very important and interesting problem is an idiopathic facial paresis (Bell's palsy). Actually the main target of scientific research is to assess the etiology (infectious, genetic, immunologic) and to find the most appropriate treatment.

    Whereas the somatotopy of finger movements has been extensively studied with neuroimaging, the neural foundations of facial movements remain elusive. Therefore, we systematically studied the neuronal correlates of voluntary facial movements using the Facial Action Coding System (FACS, Ekman et al., 2002). The facial movements performed in the MRI scanner were defined as Action Units (AUs) and were controlled by a certified FACS coder. The main goal of the study was to investigate the detailed somatotopy of the facial primary motor area (facial M1). Eighteen participants were asked to produce the following four facial movements in the fMRI scanner: AU1+2 (brow raiser), AU4 (brow lowerer), AU12 (lip corner puller) and AU24 (lip presser), each in alternation with a resting phase. Our facial movement task induced generally high activation in brain motor areas (e.g., M1, premotor cortex, supplementary motor area, putamen), as well as in the thalamus, insula, and visual cortex. BOLD activations revealed overlapping representations for the four facial movements. However, within the activated facial M1 areas, we could find distinct peak activities in the left and right hemisphere supporting a rough somatotopic upper to lower face organization within the right facial M1 area, and a somatotopic organization within the right M1 upper face part. In both hemispheres, the order was an inverse somatotopy within the lower face representations. In contrast to the right hemisphere, in the left hemisphere the representation of AU4 was more lateral and anterior compared to the rest of the facial movements. Our findings support the notion of a partial somatotopic order within the M1 face area confirming the "like attracts like" principle (Donoghue et al., 1992). AUs which are often used together or are similar are located close to each other in the motor cortex.

    Injury to the facial nerve during a face lift is a relatively rare but serious complication. A large body of literature has been dedicated toward bettering the understanding of the anatomical course of the facial nerve and the relative danger zones. Most of these prior reports, however, have focused on identifying the location of facial nerve branches based on their trajectory mostly in two dimensions and rarely in three dimensions. Unfortunately, the exact location of the facial nerve relative to palpable or visible facial landmarks is quite variable. Although the precise location of facial nerve branches is variable, its relationship to soft-tissue planes is relatively constant. The focus of this report is to improve understanding of facial soft-tissue anatomy so that safe planes of dissection during surgical undermining may be identified for each branch of the facial nerve. Certain anatomical locations more prone to injury and high-risk patient parameters are further emphasized to help minimize the risk of facial nerve injury during rhytidectomy.

    Facial expression recognition will be studied in this paper using mathematics morphology, through drawing and analyzing the whole geometry characteristics and some geometry characteristics of the interesting area of Infrared Thermal Imaging (IRTI). The results show that geometry characteristic in the interesting region of different expression are obviously different; Facial temperature changes almost with the expression at the same time. Studies have shown feasibility of facial expression recognition on the basis of IRTI. This method can be used to monitor the facial expression in real time, which can be used in auxiliary diagnosis and medical on disease.

  9. Social Use of Facial Expressions in Hylobatids.

    Linda Scheider

    Full Text Available Non-human primates use various communicative means in interactions with others. While primate gestures are commonly considered to be intentionally and flexibly used signals, facial expressions are often referred to as inflexible, automatic expressions of affective internal states. To explore whether and how non-human primates use facial expressions in specific communicative interactions, we studied five species of small apes (gibbons by employing a newly established Facial Action Coding System for hylobatid species (GibbonFACS. We found that, despite individuals often being in close proximity to each other, in social (as opposed to non-social contexts the duration of facial expressions was significantly longer when gibbons were facing another individual compared to non-facing situations. Social contexts included grooming, agonistic interactions and play, whereas non-social contexts included resting and self-grooming. Additionally, gibbons used facial expressions while facing another individual more often in social contexts than non-social contexts where facial expressions were produced regardless of the attentional state of the partner. Also, facial expressions were more likely 'responded to' by the partner's facial expressions when facing another individual than non-facing. Taken together, our results indicate that gibbons use their facial expressions differentially depending on the social context and are able to use them in a directed way in communicative interactions with other conspecifics.

    The rapid detection of emotional signals from facial expressions is fundamental for human social interaction. The personality factor of neuroticism modulates the processing of various types of emotional facial expressions; however, its effect on the detection of emotional facial expressions remains unclear. In this study, participants with high- and low-neuroticism scores performed a visual search task to detect normal expressions of anger and happiness, and their anti-expressions within a crowd of neutral expressions. Anti-expressions contained an amount of visual changes equivalent to those found in normal expressions compared to neutral expressions, but they were usually recognized as neutral expressions. Subjective emotional ratings in response to each facial expression stimulus were also obtained. Participants with high-neuroticism showed an overall delay in the detection of target facial expressions compared to participants with low-neuroticism. Additionally, the high-neuroticism group showed higher levels of arousal to facial expressions compared to the low-neuroticism group. These data suggest that neuroticism modulates the detection of emotional facial expressions in healthy participants; high levels of neuroticism delay overall detection of facial expressions and enhance emotional arousal in response to facial expressions.

    Facial paralysis can result in serious ocular consequences. All patients with orbicularis oculi weakness in the setting of facial nerve injury should undergo a thorough ophthalmologic evaluation. The main goal of management in these patients is to protect the ocular surface and preserve visual function. Patients with expected recovery of facial nerve function may only require temporary and conservative measures to protect the ocular surface. Patients with prolonged or unlikely recovery of facial nerve function benefit from surgical rehabilitation of the periorbital complex. Current reconstructive procedures are most commonly intended to improve coverage of the eye but cannot restore blink.

    Facial angiofibromas are benign tumors presenting as firm, dome-shaped, flesh-colored to pink papules, typically on the nose and adjoining central face. Clinically and dermoscopically they can mimic melanocytic nevi or basal cell carcinomas (BCC). Reflectance confocal microscopy (RCM) is a noninvasive imaging tool that is useful in diagnosing melanocytic and non-melanocytic facial lesions. To date no studies have described the RCM features of facial angiofibromas. Herein, we present two cases of facial angiofibromas that were imaged with RCM and revealed tumor island-like structures that mimicked BCC, leading to skin biopsy.

    This article reviews the definition, etiology and evaluation, and medical and neurosurgical treatment of neuropathic facial pain. A neuropathic origin for facial pain should be considered when evaluating a patient for rhinologic surgery because of complaints of facial pain. Neuropathic facial pain is caused by vascular compression of the trigeminal nerve in the prepontine cistern and is characterized by an intermittent prickling or stabbing component or a constant burning, searing pain. Medical treatment consists of anticonvulsant medication. Neurosurgical treatment may require microvascular decompression of the trigeminal nerve. Copyright © 2014 Elsevier Inc. All rights reserved.

    Body size may be an important factor influencing the evolution of facial expression in anthropoid primates due to allometric constraints on the perception of facial movements. Given this hypothesis, I tested the prediction that observed facial mobility is positively correlated with body size in a comparative sample of nonhuman anthropoids. Facial mobility, or the variety of facial movements a species can produce, was estimated using a novel application of the Facial Action Coding System (FACS). I used FACS to estimate facial mobility in 12 nonhuman anthropoid species, based on video recordings of facial activity in zoo animals. Body mass data were taken from the literature. I used phylogenetic generalized least squares (PGLS) to perform a multiple regression analysis with facial mobility as the dependent variable and two independent variables: log body mass and dummy-coded infraorder. Together, body mass and infraorder explain 92% of the variance in facial mobility. However, the partial effect of body mass is much stronger than for infraorder. The results of my study suggest that allometry is an important constraint on the evolution of facial mobility, which may limit the complexity of facial expression in smaller species. More work is needed to clarify the perceptual bases of this allometric pattern.

    Resumimos en este trabajo nuestra experiencia en el tratamiento quirúrgico de la parálisis facial y que comprende una serie de 203 intervenciones que hemos tenido oportunidad de practicar hasta Mayo de 1980. Esta casuística ha sido seleccionada en pacientes de nuestra clientela privada y en aquellos pacientes atendidos en los servicios sociales del Hospital San José, Dpto de Otorrinolaringología, algunos de ellos operados por el personal de nuestro departamento. El número total de intervenciones quirúrgicas de hueso temporal practicadas en estos 26 años en el Instituto de Cirugía del Oído y en el Hospital San José asciende
    a 5.345 de las cuales 203 corresponden a Cirugía del Nervio Facial, no solo en su trayecto timpánico y mastoideo sino en su trayecto laberintico. Durante los primeros 10 años de nuestra práctica audioquirúrgica fueron muy escasas las intervenciones practicadas, bien por el temor de los pacientes a aceptar esta cirugía o bien por la falta de referencia o confianza de otros especialistas. Con los progresos de la moderna cirugía y la mejoria en
    nuestros resultados la confianza ha renacido y es así como en los últimos 3 años hemos tenido oportunidad de operar cerca de 30 pacientes.

    La mayor parte de nuestra casuística corresponde a lesiones idiopáticas de Bell, en un 80% de los casos, un 10% de lesiones post-traumáticas y el resto a otro tipo de patología. La vida moderna y los riesgos a los cuales estamos sometidos hace que las lesiones del nervio facial sean cada día más frecuentes, por accidentes de trabajo, deportes (equitación, boxeo, natación, esquí, etc', heridas con armas de fuego, accidentes de tráfico y también

    Four experiments were conducted with 5- to 11-year-olds and adults to investigate whether facial identity, facial speech, emotional expression, and gaze direction are processed independently of or in interaction with one another. In a computer-based, speeded sorting task, participants sorted faces according to facial identity while disregarding facial speech, emotional expression, and gaze direction or, alternatively, according to facial speech, emotional expression, and gaze direction while disregarding facial identity. Reaction times showed that children and adults were able to direct their attention selectively to facial identity despite variations of other kinds of face information, but when sorting according to facial speech and emotional expression, they were unable to ignore facial identity. In contrast, gaze direction could be processed independently of facial identity in all age groups. Apart from shorter reaction times and fewer classification errors, no substantial change in processing facial information was found to be correlated with age. We conclude that adult-like face processing routes are employed from 5 years of age onward.

    Many practitioners find the complexity of facial growth overwhelming and thus merely observe and accept the clinical features of atypical growth and do not comprehend the long-term consequences. Facial growth and development is a strictly controlled biological process. Normal growth involves ongoing bone remodeling and positional displacement. Atypical growth begins when this biological balance is disturbed With the understanding of these processes, clinicians can adequately assess patients and determine the causes of these atypical facial growth patterns and design effective treatment plans. This is the first of a series of articles which addresses normal facial growth, atypical facial growth, patient assessment, causes of atypical facial growth, and guiding facial growth back to normal.

  8. Fast Facial Detection by Depth Map Analysis

    2013-01-01

    Full Text Available In order to obtain correct facial recognition results, one needs to adopt appropriate facial detection techniques. Moreover, the effects of facial detection are usually affected by the environmental conditions such as background, illumination, and complexity of objectives. In this paper, the proposed facial detection scheme, which is based on depth map analysis, aims to improve the effectiveness of facial detection and recognition under different environmental illumination conditions. The proposed procedures consist of scene depth determination, outline analysis, Haar-like classification, and related image processing operations. Since infrared light sources can be used to increase dark visibility, the active infrared visual images captured by a structured light sensory device such as Kinect will be less influenced by environmental lights. It benefits the accuracy of the facial detection. Therefore, the proposed system will detect the objective human and face firstly and obtain the relative position by structured light analysis. Next, the face can be determined by image processing operations. From the experimental results, it demonstrates that the proposed scheme not only improves facial detection under varying light conditions but also benefits facial recognition.

  10. Facial Mimicry in its Social Setting

    2015-08-01

    Full Text Available In interpersonal encounters, individuals often exhibit changes in their own facial expressions in response to emotional expressions of another person. Such changes are often called facial mimicry. While this tendency first appeared to be an automatic tendency of the perceiver to show the same emotional expression as the sender, evidence is now accumulating that situation, person, and relationship jointly determine whether and for which emotions such congruent facial behavior is shown. We review the evidence regarding the moderating influence of such factors on facial mimicry with a focus on understanding the meaning of facial responses to emotional expressions in a particular constellation. From this, we derive recommendations for a research agenda with a stronger focus on the most common forms of encounters, actual interactions with known others, and on assessing potential mediators of facial mimicry. We conclude that facial mimicry is modulated by many factors: attention deployment and sensitivity, detection of valence, emotional feelings, and social motivations. We posit that these are the more proximal causes of changes in facial mimicry due to changes in its social setting.

    Immunobiological study is a key to revealing the important basis of facial nerve repair and regeneration for both research and development of clinic treatments. The microenvironmental changes around an injuried facial motoneuron, i.e., the aggregation and expression of various types of immune cells and molecules in a dynamic equilibrium, impenetrate from the start to the end of the repair of an injured facial nerve. The concept of "immune microenvironment for facial nerve repair and regeneration", mainly concerns with the dynamic exchange between expression and regulation networks and a variaty of immune cells and immune molecules in the process of facial nerve repair and regeneration for the maintenance of a immune microenvironment favorable for nerve repair.Investigation on microglial activation and recruitment, T cell behavior, cytokine networks, and immunological cellular and molecular signaling pathways in facial nerve repair and regeneration are the current hot spots in the research on immunobiology of facial nerve injury. The current paper provides a comprehensive review of the above mentioned issues. Research of these issues will eventually make immunological interventions practicable treatments for facial nerve injury in the clinic.

    Recent advantages in the anatomical understanding of the face have turned the focus toward the subcutaneous and deep facial fat compartments. During facial aging, these fat-filled compartments undergo substantial changes along with other structures in the face. Soft tissue filler and fat grafting are valid methods to fight the signs of facial aging, but little is known about their precise effect on the facial fat. This narrative review summarizes the current knowledge about the facial fat compartments in terms of anatomical location, histologic appearance, immune-histochemical characteristics, cellular interactions, and therapeutic options. Three different types of facial adipose tissue can be identified, which are located either superficially (dermal white adipose tissue) or deep (subcutaneous white adipose tissue): fibrous (perioral locations), structural (major parts of the midface), and deposit (buccal fat pad and deep temporal fat pad). These various fat types differ in the size of the adipocytes and the collagenous composition of their extracellular matrix and thus in their mechanical properties. Minimal invasive (e.g., soft tissue fillers or fat grafting) and surgical interventions aiming to restore the youthful face have to account for the different fat properties in various facial areas. However, little is known about the macro- and microscopic characteristics of the facial fat tissue in different compartments and future studies are needed to reveal new insights to better understand the process of aging and how to fight its signs best.

  14. Facial nerve palsy and hemifacial spasm.

    Valls-Solé, Josep

    2013-01-01

    Facial nerve lesions are usually benign conditions even though patients may present with emotional distress. Facial palsy usually resolves in 3-6 weeks, but if axonal degeneration takes place, it is likely that the patient will end up with a postparalytic facial syndrome featuring synkinesis, myokymic discharges, and hemifacial mass contractions after abnormal reinnervation. Essential hemifacial spasm is one form of facial hyperactivity that must be distinguished from synkinesis after facial palsy and also from other forms of facial dyskinesias. In this condition, there can be ectopic discharges, ephaptic transmission, and lateral spread of excitation among nerve fibers, giving rise to involuntary muscle twitching and spasms. Electrodiagnostic assessment is of relevance for the diagnosis and prognosis of peripheral facial palsy and hemifacial spasm. In this chapter the most relevant clinical and electrodiagnostic aspects of the two disorders are reviewed, with emphasis on the various stages of facial palsy after axonal degeneration, the pathophysiological mechanisms underlying the various features of hemifacial spasm, and the cues for differential diagnosis between the two entities.

    An intimate knowledge of facial nerve anatomy is critical to avoid its inadvertent injury during rhytidectomy, parotidectomy, maxillofacial fracture reduction, and almost any surgery of the head and neck. Injury to the frontal and marginal mandibular branches of the facial nerve in particular can lead to obvious clinical deficits, and areas where these nerves are particularly susceptible to injury have been designated danger zones by previous authors. Assessment of facial nerve function is not limited to its extratemporal anatomy, however, as many clinical deficits originate within its intratemporal and intracranial components. Similarly, the facial nerve cannot be considered an exclusively motor nerve given its contributions to taste, auricular sensation, sympathetic input to the middle meningeal artery, and parasympathetic innervation to the lacrimal, submandibular, and sublingual glands. The constellation of deficits resulting from facial nerve injury is correlated with its complex anatomy to help establish the level of injury, predict recovery, and guide surgical management.

    This paper introduces a novel low-computation discriminative regions representation for expression analysis task. The proposed approach relies on interesting studies in psychology which show that most of the descriptive and responsible regions for facial expression are located around some face parts. The contributions of this work lie in the proposition of new approach which supports automatic facial expression recognition based on automatic regions selection. The regions selection step aims to select the descriptive regions responsible or facial expression and was performed using Mutual Information (MI) technique. For facial feature extraction, we have applied Local Binary Patterns Pattern (LBP) on Gradient image to encode salient micro-patterns of facial expressions. Experimental studies have shown that using discriminative regions provide better results than using the whole face regions whilst reducing features vector dimension.

    Recently, compressive sensing (CS) has attracted increasing attention in the areas of signal processing, computer vision and pattern recognition. In this paper, a new method based on the CS theory is presented for robust facial expression recognition. The CS theory is used to construct a sparse representation classifier (SRC). The effectiveness and robustness of the SRC method is investigated on clean and occluded facial expression images. Three typical facial features, i.e., the raw pixels, Gabor wavelets representation and local binary patterns (LBP), are extracted to evaluate the performance of the SRC method. Compared with the nearest neighbor (NN), linear support vector machines (SVM) and the nearest subspace (NS), experimental results on the popular Cohn-Kanade facial expression database demonstrate that the SRC method obtains better performance and stronger robustness to corruption and occlusion on robust facial expression recognition tasks.

    Most of the facial trauma in the United States is treated in trauma centers in large urban or university medical centers, with limited trauma care taking place in our military medical treatment facilities. In many cases, active duty facial trauma surgeons may lack the current experience necessary for the optimal care of facial wounds of our inquired military personnel in the early stages of the conflict. Consequently, the skills of the reservist trauma surgeons who staff our civilian trauma centers and who care for facial trauma victims daily will be critical in caring for our wounded. These "trauma-current" reservists may act as a cadre of practiced surgeons to aid those with less experience. A plan for refresher training of active duty facial trauma surgeons is presented.

    Full Text Available Abstract Acro-cardio-facial syndrome (ACFS is a rare genetic disorder characterized by split-hand/split-foot malformation (SHFM, facial anomalies, cleft lip/palate, congenital heart defect (CHD, genital anomalies, and mental retardation. Up to now, 9 patients have been described, and most of the reported cases were not surviving the first days or months of age. The spectrum of defects occurring in ACFS is wide, and both interindividual variability and clinical differences among sibs have been reported. The diagnosis is based on clinical criteria, since the genetic mechanism underlying ACFS is still unknown. The differential diagnosis includes other disorders with ectrodactyly, and clefting conditions associated with genital anomalies and heart defects. An autosomal recessive pattern of inheritance has been suggested, based on parental consanguinity and disease's recurrence in sibs in some families. The more appropriate recurrence risk of transmitting the disease for the parents of an affected child seems to be up to one in four. Management of affected patients includes treatment of cardiac, respiratory, and feeding problems by neonatal pediatricians and other specialists. Prognosis of ACFS is poor.

  20. Facial orientation and facial shape in extant great apes: a geometric morphometric analysis of covariation.

    Directory of Open Access Journals (Sweden)

    Dimitri Neaux

    Full Text Available The organization of the bony face is complex, its morphology being influenced in part by the rest of the cranium. Characterizing the facial morphological variation and craniofacial covariation patterns in extant hominids is fundamental to the understanding of their evolutionary history. Numerous studies on hominid facial shape have proposed hypotheses concerning the relationship between the anterior facial shape, facial block orientation and basicranial flexion. In this study we test these hypotheses in a sample of adult specimens belonging to three extant hominid genera (Homo, Pan and Gorilla. Intraspecific variation and covariation patterns are analyzed using geometric morphometric methods and multivariate statistics, such as partial least squared on three-dimensional landmarks coordinates. Our results indicate significant intraspecific covariation between facial shape, facial block orientation and basicranial flexion. Hominids share similar characteristics in the relationship between anterior facial shape and facial block orientation. Modern humans exhibit a specific pattern in the covariation between anterior facial shape and basicranial flexion. This peculiar feature underscores the role of modern humans' highly-flexed basicranium in the overall integration of the cranium. Furthermore, our results are consistent with the hypothesis of a relationship between the reduction of the value of the cranial base angle and a downward rotation of the facial block in modern humans, and to a lesser extent in chimpanzees.

  1. Automated Facial Action Coding System for dynamic analysis of facial expressions in neuropsychiatric disorders.

    Hamm, Jihun; Kohler, Christian G; Gur, Ruben C; Verma, Ragini

    2011-09-15

    Facial expression is widely used to evaluate emotional impairment in neuropsychiatric disorders. Ekman and Friesen's Facial Action Coding System (FACS) encodes movements of individual facial muscles from distinct momentary changes in facial appearance. Unlike facial expression ratings based on categorization of expressions into prototypical emotions (happiness, sadness, anger, fear, disgust, etc.), FACS can encode ambiguous and subtle expressions, and therefore is potentially more suitable for analyzing the small differences in facial affect. However, FACS rating requires extensive training, and is time consuming and subjective thus prone to bias. To overcome these limitations, we developed an automated FACS based on advanced computer science technology. The system automatically tracks faces in a video, extracts geometric and texture features, and produces temporal profiles of each facial muscle movement. These profiles are quantified to compute frequencies of single and combined Action Units (AUs) in videos, and they can facilitate a statistical study of large populations in disorders known to impact facial expression. We derived quantitative measures of flat and inappropriate facial affect automatically from temporal AU profiles. Applicability of the automated FACS was illustrated in a pilot study, by applying it to data of videos from eight schizophrenia patients and controls. We created temporal AU profiles that provided rich information on the dynamics of facial muscle movements for each subject. The quantitative measures of flatness and inappropriateness showed clear differences between patients and the controls, highlighting their potential in automatic and objective quantification of symptom severity.

    Full Text Available This paper presents a new framework to describe individual facial expression spaces, particularly addressing the dynamic diversity of facial expressions that appear as an exclamation or emotion, to create a unique space for each person. We name this framework Facial Expression Spatial Charts (FESCs. The FESCs are created using Self– Organizing Maps (SOMs and Fuzzy Adaptive Resonance Theory (ART of unsupervised neural networks. For facial images with emphasized sparse representations using Gabor wavelet filters, SOMs extract topological information in facial expression images and classify them as categories in the fixed space that are decided by the number of units on the mapping layer. Subsequently, Fuzzy ART integrates categories classified by SOMs using adaptive learning functions under fixed granularity that is controlled by the vigilance parameter. The categories integrated by Fuzzy ART are matched to Expression Levels (ELs for quantifying facial expression intensity based on the arrangement of facial expressions on Russell’s circumplex model. We designate the category that contains neutral facial expression as the basis category. Actually, FESCs can visualize and represent dynamic diversity of facial expressions consisting of ELs extracted from facial expressions. In the experiment, we created an original facial expression dataset consisting of three facial expressions—happiness, anger, and sadness— obtained from 10 subjects during 7–20 weeks at one-week intervals. Results show that the method can adequately display the dynamic diversity of facial expressions between subjects, in addition to temporal changes in each subject. Moreover, we used stress measurement sheets to obtain temporal changes of stress for analyzing psychological effects of the stress that subjects feel. We estimated stress levels of four grades using Support Vector Machines (SVMs. The mean estimation rates for all 10 subjects and for 5 subjects over more than

  4. Facial Beautification Method Based on Age Evolution

    2013-01-01

    This paper proposes a new facial beautification method using facial rejuvenation based on the age evolution. Traditional facial beautification methods only focus on the color of skin and deformation and do the transformation based on an experimental standard of beauty. Our method achieves the beauty effect by making facial image looks younger, which is different from traditional methods and is more reasonable than them. Firstly, we decompose the image into different layers and get a detail layer. Secondly, we get an age-related parameter:the standard deviation of the Gaussian distribution that the detail layer follows, and the support vector machine (SVM) regression is used to fit a function about the age and the standard deviation. Thirdly, we use this function to estimate the age of input image and generate a new detail layer with a new standard deviation which is calculated by decreasing the age. Lastly, we combine the original layers and the new detail layer to get a new face image. Experimental results show that this algo-rithm can make facial image become more beautiful by facial rejuvenation. The proposed method opens up a new way about facial beautification, and there are great potentials for applications.

    The association between congenital facial paralysis and visual development has not been thoroughly studied. Of 27 pediatric cases of congenital facial paralysis, we identified 3 patients who developed amblyopia, a visual acuity decrease caused by abnormal visual development, as comorbidity. These 3 patients had facial paralysis in the periocular region and developed amblyopia on the paralyzed side. They started treatment by wearing an eye patch immediately after diagnosis and before the critical visual developmental period; all patients responded to the treatment. Our findings suggest that the incidence of amblyopia in the cases of congenital facial paralysis, particularly the paralysis in the periocular region, is higher than that in the general pediatric population. Interestingly, 2 of the 3 patients developed anisometropic amblyopia due to the hyperopia of the affected eye, implying that the periocular facial paralysis may have affected the refraction of the eye through yet unspecified mechanisms. Therefore, the physicians who manage facial paralysis should keep this pathology in mind, and when they see pediatric patients with congenital facial paralysis involving the periocular region, they should consult an ophthalmologist as soon as possible. © 2016 S.

    2014-08-01

    The purpose of this article is to provide the facial plastic surgeon with anatomical and embryologic evidence to support the use of the deep plane technique for optimal treatment of facial aging. A detailed description of the procedure is provided to allow safe and consistent performance. Insights into anatomical landmarks, technical nuances, and alternative approaches for facial variations are presented. The following points will be further elucidated in the article. The platysma muscle/submuscular aponeurotic system/galea are the continuous superficial cervical fascia encompassing the majority of facial fat, and this superficial soft tissue envelope is poorly anchored to the face. The deep cervical fascia binds the structural aspects of the face and covers the facial nerve and buccal fat pad. Facial aging is mainly due to gravity's long-term effects on the superficial soft tissue envelope, with more subtle effects on the deeper structural compartments. The deep plane is the embryologic cleavage plane between these fascial layers, and is the logical place for facial dissection. The deep plane allows access to the buccal fat pad for treatment of jowling. Soft tissue mobilization is maximized in deep plane dissections and requires careful hairline planning. Flap advancement creates tension only at the fascia level allowing natural, tension-free skin closure, and long-lasting outcomes. The deep plane advancement flap is well vascularized and resistant to complications.

    Full Text Available The improvement of a patient’s facial appearance is one of the main goals of contemporary orthodontic treatment. The aim of this investigation was to evaluate the difference in facial proportions between attractive and anonymous females in order to establish objective facial features which are widely considered as beautiful. The study included two groups: first group consisted of 83 Caucasian female subjects between 22 and 28 years of age who were selected from the population of students at the University of Belgrade, and the second group included 24 attractive celebrity Caucasian females. The en face facial photographs were taken in natural head position (NHP. Numerous parameters were recorded on these photographs, in order to establish facial symmetry and correlation with the ideal set of proportions. This study showed significant difference between anonymous and attractive females. Attractive females showed smaller face in general and uniformity of the facial thirds and fifths, and most of the facial parameters meet the criteria of the ideal proportions.

    We asked whether the identification of emotional facial expressions (FEs) involves the simultaneous perception of the facial configuration or the detection of emotion-specific diagnostic cues. We recorded at high speed (500 frames s-1) the unfolding of the FE in five actors, each expressing six emotions (anger, surprise, happiness, disgust, fear, sadness). Recordings were coded every 10 frames (20 ms of real time) with the Facial Action Coding System (FACS, Ekman et al 2002, Salt Lake City, UT: Research Nexus eBook) to identify the facial actions contributing to each expression, and their intensity changes over time. Recordings were shown in slow motion (1/20 of recording speed) to one hundred observers in a forced-choice identification task. Participants were asked to identify the emotion during the presentation as soon as they felt confident to do so. Responses were recorded along with the associated response times (RTs). The RT probability density functions for both correct and incorrect responses were correlated with the facial activity during the presentation. There were systematic correlations between facial activities, response probabilities, and RT peaks, and significant differences in RT distributions for correct and incorrect answers. The results show that a reliable response is possible long before the full FE configuration is reached. This suggests that identification is reached by integrating in time individual diagnostic facial actions, and does not require perceiving the full apex configuration.

    Injuries in the parotid and masseter region can cause serious impairment secondary to damage of important anatomical structures. Sialocele is observed as facial swelling associated with parotid duct rupture due to trauma. The aim of this paper is to report a case of a giant traumatic sialocele in the parotid gland, secondary to a knife lesion in a 40-year-old woman. Conservative measures could not promote clinical resolution and a surgical intervention for the placement of a vacuum drain was selected. Under local anesthesia, a small incision was performed adjacent to parotid duct papilla, followed by muscular divulsion and draining of significant amount of saliva. An active vacuum suction drain was placed for 15 days, aiming to form a new salivary duct. This technique was shown to be a safe, effective and low-cost option, leading to complete resolution and no recurrence after 28 months of follow up.

    The face is a vital component of one’s personality and body image. There are a vast number of variables that influence recovery and rehabilitation from acquired facial trauma many of which are psychological in nature. The present paper presents the various psychological issues one comes across in facial trauma patients. These may range from body image issues to post-traumatic stress disorder symptoms accompanied by anxiety and depression. Issues related to facial and body image affecting social life and general quality of life are vital and the plastic surgeon should be aware of such issues and competent to deal with them in patients and families.

    Full Text Available Face recognition is an important biometric method because of its potential applications in many fields, such as access control, surveillance, and human-computer interaction. In this paper, a face recognition system that fuses the outputs of three face recognition systems based on Gabor jets is presented. The first system uses the magnitude, the second uses the phase, and the third uses the phase-weighted magnitude of the jets. The jets are generated from facial landmarks selected using three selection methods. It was found out that fusing the facial features gives better recognition rate than either facial feature used individually regardless of the landmark selection method.

    In the modern medical era, facial paralysis is linked with the name of Charles Bell. This disease, which is usually unilateral and is a peripheral facial palsy, causes facial muscle weakness in the affected side. Bell gave a complete description of the disease; but historically other physicians had described it several hundred years prior although it had been ignored for different reasons, such as the difficulty of the original text language. The first and the most famous of these physicians who described this disease was Mohammad Ibn Zakaryya Razi (Rhazes). In this article, we discuss his opinion.

    Bullous leukemia cutis is an uncommon clinical manifestation of cutaneous infiltration by leukemic cells, from B-cell chronic lymphocytic leukemia. We present the case of a 67-year-old, female, chronic lymphocytic leukemia patient. She was taking chlorambucil and developed facial edema with erythema and warmth, misjudged as facial cellulitis. Two days later, she developed bullous lesions in the arms, legs, neck and face. The histopathology of facial and bullous lesions confirmed leukemia cutis. All lesions disappeared following the administration of rituximab combined with cycles of fludarabine and cyclophosphamide. Although soft tissue infections are common complications in patients undergoing chemotherapy, leukemia cutis can also resemble cellulitis. PMID:27192532

    Intratemporal vascular tumors involving the facial nerve are rare benign lesions. Because of their variable clinical features, they are often misdiagnosed preoperatively. This study presents a series of 21 patients with such lesions managed from 1977 to 1994. Facial nerve dysfunction was the most common complaint, present in 60% of the cases, followed by hearing loss, present in 40% of cases. High-resolution computed tomography, magnetic resonance imaging with gadolinium, and a high index of clinical suspicion is required for preoperative diagnosis of these lesions. Early surgical resection of these tumors permits acceptable return of facial nerve function in many patients. ImagesFigure 1Figure 2Figure 3 PMID:17170963

    Decisions about whom to trust are biased by stable facial traits such as attractiveness, similarity to kin, and perceived trustworthiness. Research addressing the validity of facial trustworthiness or its basis in facial features is scarce, and the results have been inconsistent. We measured male trustworthiness operationally in trust games in which participants had options to collaborate for mutual financial gain or to exploit for greater personal gain. We also measured facial (bizygomatic) width (scaled for face height) because this is a sexually dimorphic, testosterone-linked trait predictive of male aggression. We found that men with greater facial width were more likely to exploit the trust of others and that other players were less likely to trust male counterparts with wide rather than narrow faces (independent of their attractiveness). Moreover, manipulating this facial-width ratio with computer graphics controlled attributions of trustworthiness, particularly for subordinate female evaluators.

    Although symmetry is hailed as a fundamental goal of aesthetic and reconstructive surgery, our tools for measuring this outcome have been limited and subjective. With the advent of three-dimensional photogrammetry, surface geometry can be captured, manipulated, and measured quantitatively. Until now, few normative data existed with regard to facial surface symmetry. Here, we present a method for reproducibly calculating overall facial symmetry and present normative data on 100 subjects. We enrolled 100 volunteers who underwent three-dimensional photogrammetry of their faces in repose. We collected demographic data on age, sex, and race and subjectively scored facial symmetry. We calculated the root mean square deviation (RMSD) between the native and reflected faces, reflecting about a plane of maximum symmetry. We analyzed the interobserver reliability of the subjective assessment of facial asymmetry and the quantitative measurements and compared the subjective and objective values. We also classified areas of greatest asymmetry as localized to the upper, middle, or lower facial thirds. This cluster of normative data was compared with a group of patients with subtle but increasing amounts of facial asymmetry. We imaged 100 subjects by three-dimensional photogrammetry. There was a poor interobserver correlation between subjective assessments of asymmetry (r = 0.56). There was a high interobserver reliability for quantitative measurements of facial symmetry RMSD calculations (r = 0.91-0.95). The mean RMSD for this normative population was found to be 0.80 ± 0.24 mm. Areas of greatest asymmetry were distributed as follows: 10% upper facial third, 49% central facial third, and 41% lower facial third. Precise measurement permitted discrimination of subtle facial asymmetry within this normative group and distinguished norms from patients with subtle facial asymmetry, with placement of RMSDs along an asymmetry ruler.

    Individuals with facial paralysis and distorted facial expressions and movements secondary to a facial neuromotor disorder experience substantial physical, psychological, and social disability. Previously, facial rehabilitation has not been widely available or considered to be of much benefit. An emerging rehabilitation science of neuromuscular reeducation and evidence for the efficacy of facial neuromuscular reeducation, a process of facilitating the return of intended facial movement patterns and eliminating unwanted patterns of facial movement and expression, may provide patients with disorders of facial paralysis or facial movement control opportunity for the recovery of facial movement and function. We provide a brief overview of the scientific rationale for facial neuromuscular reeducation in the structure and function of the facial neuromotor system, the neuropsychology of facial expression, and relations among expressions, movement, and emotion. The primary purpose is to describe principles of neuromuscular reeducation, assessment and outcome measures, approach to treatment, the process, including surface-electromyographic biofeedback as an adjunct to reeducation, and the goal of enhancing the recovery of facial expression and function in a patient-centered approach to facial rehabilitation.

    Recent studies suggest that judgments of facial masculinity reflect more than sexually dimorphic shape. Here, we investigated whether the perception of masculinity is influenced by facial cues to body height and weight. We used the average differences in three-dimensional face shape of forty men and forty women to compute a morphological masculinity score, and derived analogous measures for facial correlates of height and weight based on the average face shape of short and tall, and light and heavy men. We found that facial cues to body height and weight had substantial and independent effects on the perception of masculinity. Our findings suggest that men are perceived as more masculine if they appear taller and heavier, independent of how much their face shape differs from women's. We describe a simple method to quantify how body traits are reflected in the face and to define the physical basis of psychological attributions.

    Camouflaging Facial Emphysema, as is defined in this paper, is the result of a simple technique used by the patient to deform his face in order to prevent recognition at a police identity parade. The patient performs two punctures in the mucosa at the rear of the upper lip and, after several Valsalva manoeuvres, manages to deform his face in less than 15 min by inducing subcutaneous facial emphysema. The examination shows an accumulation of air in the face, with no laterocervical, mediastinal or thoracic affectations. The swelling is primarily observed in the eyelids and the orbital and zygomatic regions, whereas it is less prominent in other areas of the face. Patients therefore manage to avoid recognition in properly conducted police identity parades. Only isolated cases of self-induced facial emphysema have been reported to date among psychiatric patients and prison inmates. However, the facial emphysema herein described exhibits specific characteristics of significant medical, deontological, social, police-related, and legal implications.

    Full Text Available Facial expression recognition is one of the most active fields of research. Many facial expression recognition methods have been developed and implemented. Neural networks (NNs have capability to undertake such pattern recognition tasks. The key factor of the use of NN is based on its characteristics. It is capable in conducting learning and generalizing, non-linear mapping, and parallel computation. Backpropagation neural networks (BPNNs are the approach methods that mostly used. In this study, BPNNs were used as classifier to categorize facial expression images into seven-class of expressions which are anger, disgust, fear, happiness, sadness, neutral and surprise. For the purpose of feature extraction tasks, three discrete wavelet transforms were used to decompose images, namely Haar wavelet, Daubechies (4 wavelet and Coiflet (1 wavelet. To analyze the proposed method, a facial expression recognition system was built. The proposed method was tested on static images from JAFFE database.

    The diagnosis of a permanent facial paralysis can be devastating to a patient, because of the cosmetic, functional and psychological disorders. Our society places on physical appearance and leads to isolation of patients who are embarrassed with their paralyzed face. The objectives of the facial rehabilitation is to correct the functional and cosmetic losses of the patient. The main functional goals are to protect the eye and reestablish oral competence. The primary cosmetic goals are to create balance and symmetry of the face at rest and to reestablish the coordinated movement of the facial musculature. The surgeon should be familiar with the variety of options available so that an individual plan can be developed based on each patient's clinical picture. History of the facial paralysis, its etiology and the duration of the paralysis are of particular interest as they orientate the rehabilitation plan strategy.

    Facial reconstruction using 3-D computer graphics is being used in our institute as a routine procedure in forensic cases as well as for skulls of historical and archaeological interest. Skull and facial data from living subjects is acquired using an optical laser scanning system. For the production of the reconstructed image, we employ facial reconstruction software which is constructed using the TCL/Tk scripting language, the latter making use of the C3D system. The computer image may then be exported to enable the production of a solid model, employing, for example, stereolithography. The image can also be modified within an identikit system which allows the addition of facial features as appropriate.

    So, Edmund Cheung

    2010-10-01

    Cervical traction is a frequently used treatment in rehabilitation clinics for cervical spine problems. This modality works, in principle, by decompressing the spinal cord or its nerve roots by applying traction on the cervical spine through a harness placed over the mandible (Olivero et al., Neurosurg Focus 2002;12:ECP1). Previous reports on treatment complications include lumbar radicular discomfort, muscle injury, neck soreness, and posttraction pain (LaBan et al., Arch Phys Med Rehabil 1992;73:295-6; Lee et al., J Biomech Eng 1996;118:597-600). Here, we report the first case of unilateral facial nerve paralysis developed after 4 wks of intermittent cervical traction therapy. Nerve conduction velocity examination revealed a peripheral-type facial nerve paralysis. Symptoms of facial nerve paralysis subsided after prednisolone treatment and suspension of traction therapy. It is suspected that a misplaced or an overstrained harness may have been the cause of facial nerve paralysis in this patient. Possible causes were (1) direct compression by the harness on the right facial nerve near its exit through the stylomastoid foramen; (2) compression of the right external carotid artery by the harness, causing transient ischemic injury at the geniculate ganglion; or (3) coincidental herpes zoster virus infection or idiopathic Bell's palsy involving the facial nerve.

    Forensic facial reconstruction can be used to identify unknown human remains when other techniques fail. Through this article, we attempt to review the different methods of facial reconstruction reported in literature. There are several techniques of doing facial reconstruction, which vary from two dimensional drawings to three dimensional clay models. With the advancement in 3D technology, a rapid, efficient and cost effective computerized 3D forensic facial reconstruction method has been developed which has brought down the degree of error previously encountered. There are several methods of manual facial reconstruction but the combination Manchester method has been reported to be the best and most accurate method for the positive recognition of an individual. Recognition allows the involved government agencies to make a list of suspected victims'. This list can then be narrowed down and a positive identification may be given by the more conventional method of forensic medicine. Facial reconstruction allows visual identification by the individual's family and associates to become easy and more definite.

    This paper introduces a tensor perceptual color framework (TPCF) for facial expression recognition (FER), which is based on information contained in color facial images. The TPCF enables multi-linear image analysis in different color spaces and demonstrates that color components provide additional information for robust FER. Using this framework, the components (in either RGB, YCbCr, CIELab or CIELuv space) of color images are unfolded to two-dimensional (2- D) tensors based on multi-linear algebra and tensor concepts, from which the features are extracted by Log-Gabor filters. The mutual information quotient (MIQ) method is employed for feature selection. These features are classified using a multi-class linear discriminant analysis (LDA) classifier. The effectiveness of color information on FER using low-resolution and facial expression images with illumination variations is assessed for performance evaluation. Experimental results demonstrate that color information has significant potential to improve emotion recognition performance due to the complementary characteristics of image textures. Furthermore, the perceptual color spaces (CIELab and CIELuv) are better overall for facial expression recognition than other color spaces by providing more efficient and robust performance for facial expression recognition using facial images with illumination variation.

    Recently discovered cranial fossils from the Oligocene deposits of the Fayum depression in Egypt provide many details of the facial morphology of Aegyptopithecus zeuxis. Similar features are found in the Miocene hominoid Afropithecus turkanensis. Their presence is the first good evidence of a strong phenetic link between the Oligocene and Miocene hominoids of Africa. A comparison of trait lists emphasizes the similarities of the two fossil species, and leads us to conclude that the two fossil genera share many primitive facial features. In addition, we studied facial morphology using finite-element scaling analysis and found that the two genera show similarities in morphological integration, or the way in which biological landmarks relate to one another in three dimensions to define the form of the organism. Size differences between the two genera are much greater than the relatively minor shape differences. Analysis of variability in landmark location among the four Aegyptopithecus specimens indicates that variability within the sample is not different from that found within two samples of modern macaques. We propose that the shape differences found among the four Aegyptopithecus specimens simply reflect individual variation in facial characteristics, and that the similarities in facial morphology between Aegyptopithecus and Afropithecus probably represent a complex of primitive facial features retained over millions of years.

    Background: Studies have not adequately compared subjective/objective ratings of female dermatology patients including patients presenting for cosmetic procedures. Objective: To examine objective versus subjective facial attractiveness ratings, demographic variables, and how men versus women judge female facial attractiveness. Methods: Sixty-five women (mean 42 years) presenting to a dermatology office. Subjects filled out a demographic and attractiveness questionnaire and were photographed. Four judges (2 male and 2 female) rated the photographs on a predefined 1 to 7 scale. Results: Mean subjective rating (subjects rating themselves) was 4.85 versus 3.61 for objective rating (judges rating subjects) (p<0.001). The mean age of subjects self-rating (subjective rating) who rated themselves in the 5 to 7 range was 39 years; the mean age of subjects self-rating (subjective rating) who rated themselves in the 3 to 4 range was 45 years (p=0.053). The mean age of subjects objectively rated by judges in the 5 to 7 range was 33 years; the mean age of subjects objectively rated by judges in the 3 to 4 range was 43 years (p<0.001); and the mean age of subjects objectively rated by judges in the 1 to 2 range was 50 years (p<0.001). The mean subjective rating (subjects rating themselves) for married women was 4.55 versus 5.27 for unmarried women (p=0.007); the mean objective rating (judges rating subjects) was 3.22 versus 4.15 (p<0.001). The mean objective rating by male judges was 3.09 versus 4.12 for female judges (p<0.001) Conclusion: Female patients presenting to a dermatology office rated themselves more attractive than did judges who viewed photographs of the subjects. Age and marital status were significant factors, and male judges rated attractiveness lower than female judges. Limitations of the study, implications, and suggestions for future research directions are discussed. PMID:21203353

The parotid gland is the first lymph node echelon in the regional dissemination of frontal, orbital and nasal cutaneous melanomas. Although the lymphoscintigraphy has been become a standard diagnostic technique for studying melanomas, it is not exempt of inconveniences. Material and methods. We present the case of a patient with frontal melanoma and sentinel nodes in the parotid region, and we discuss the peculiarities, advantages and disadvantages of using this technique in this region. Conclusions. Although it has been proved that an affected sentinel lymph node is the most important prognostic factor for recurrence and survival, we believe that this is a technique under study, and that its influence on survival should be demonstrated with regard to the alternative of clinical monitoring. It should therefore be indicated in specific cases with greater probabilities of metastases.

    We present the results of a preliminary study on the use of 3-D software (Photomodeler) for identification purposes. Perpetrators may be photographed or filmed by surveillance systems. The police may wish to have these images compared to photographs of suspects. The surveillance imagery will often consist of many images of the same person taken from different angles. We wanted to see if it was possible to combine such a suite of images in useful 3-D renderings of facial proportions.Fifteen male adults were photographed from four different angles. Based on these photographs, a 3-D wireframe model was produced by Photomodeler. The wireframe models were then rotated to full lateral and frontal views, and compared to like sets of photographs of the subjects. In blind trials, 9/15 of the wireframe models were assigned to the correct sets of photographs. In five/15 cases, the wireframe models were assigned to several sets, including the correct set. Only in one case was a wireframe model not assigned to a correct set of photographs at all.

    Potter's reno-facial syndrome is a rare innate abnormality. We bring 4 observations repertoried at the maternity of military hospital of Tunis over a period of 6 years (1997 - 2002). The purpose of our work is to determine after a review of the literature the echographic and foetopathologic characteristics, and the forecast of this syndrome. The frequency of the bilateral renale agenesis is of 0.27 per thousand. Positive diagnosis bases essentially on the ultrasound of the 2th, or the 3-th trimester. The signs of appeal are essentially the oligoamnios associated to an hypotrophy. The caryotype is systematic to eliminate an associeted chromosomic abnormality. Foetopathologic exam is usefull for the diagnosis. Main abnormality except the urinary pathology is the lung hypoplasia. Therapeutic interruption of the pregnancy in this situation not compatible with the extra-uterine life., only type IV authorize the development of the pregnancy according to echographic data and of foetal urinaire biochemistry. We insist on the early practice of the morphological ultrasound between 20 - 22 weeks for the diagnosis of foetal abnormalities and the place of the genetic advice in association with the geneticist in the coverage of the couple.

    Introduccion. La expresion facial de las emociones tiene una funcion social importante que facilita la interaccion entre las personas. Este proceso tiene una base neurologica, que no se aisla del contexto ni de la experiencia acumulada por la interaccion entre las personas en dicho contexto. Sin embargo, hasta la fecha, no se conocen con claridad los efectos de la experiencia sobre la percepcion de las emociones. Objetivos. Discutir que funcion desempeña la experiencia en el reconocimiento de la expresion facial de las emociones y analizar los sesgos que las experiencias negativas y positivas podrian tener sobre la percepcion emocional. Desarrollo. La maduracion de las estructuras que soportan la capacidad para reconocer la emocion pasa por un periodo sensible durante la adolescencia, donde la experiencia adquirida puede tener mayor impacto sobre el reconocimiento emocional. Experiencias de abuso, maltrato, abandono, guerras o estres generan un sesgo hacia las expresiones de ira y tristeza. De igual manera, las experiencias positivas dan lugar a un sesgo hacia la expresion de alegria. Conclusiones. Solo cuando las personas son capaces de utilizar la expresion facial de las emociones como un canal de comprension y expresion interaccionaran de manera adecuada con su entorno. Este entorno, a su vez, dara lugar a experiencias que modulan dicha capacidad. Por lo tanto, es un proceso autorregulatorio que puede ser dirigido a traves de la implementacion de programas de intervencion sobre los aspectos emocionales.

    A facial recognition system is a computer application for automatically identifying or verifying a person from a digital image or a video frame from a video source. One of the way is to do this is by comparing selected facial features from the image and a facial database.It is typically used in security systems and can be compared to other biometrics such as fingerprint or eye iris recognition systems. In this paper we focus on 3-D facial recognition system and biometric facial recognision system. We do critics on facial recognision system giving effectiveness and weaknesses. This paper also introduces scope of recognision system in India.

    Objective: To evaluate the measurement accuracy of three-dimensional (3D) facial scanners for facial deformity patients from oral clinic. Methods: 10 patients in different types of facial deformity from oral clinical were included. Three 3D digital face models for each patient were obtained by three facial scanners separately (line laser scanner from Faro for reference, stereophotography scanner from 3dMD and structured light scanner from FaceScan for test). For each patient, registration based on Iterative Closest Point (ICP) algorithm was executed to align two test models (3dMD data & Facescan data) to the reference models (Faro data in high accuracy) respectively. The same boundaries on each pair models (one test and one reference models) were obtained by projection function in Geomagic Stuido 2012 software for trimming overlapping region, then 3D average measurement errors (3D errors) were calculated for each pair models also by the software. Paired t-test analysis was adopted to compare the 3D errors of two test facial scanners (10 data for each group). 3D profile measurement accuracy (3D accuracy) that is integrated embodied by average value and standard deviation of 10 patients' 3D errors were obtained by surveying analysis for each test scanner finally. Results: 3D accuracies of 2 test facial scanners in this study for facial deformity were 0.44+/-0.08 mm and 0.43+/-0.05 mm. The result of structured light scanner was slightly better than stereophotography scanner. No statistical difference between them. Conclusions: Both test facial scanners could meet the accuracy requirement (0.5mm) of 3D facial data acquisition for oral clinic facial deformity patients in this study. Their practical measurement accuracies were all slightly lower than their nominal accuracies.

  20. The MPI facial expression database--a validated database of emotional and conversational facial expressions.

    Full Text Available The ability to communicate is one of the core aspects of human life. For this, we use not only verbal but also nonverbal signals of remarkable complexity. Among the latter, facial expressions belong to the most important information channels. Despite the large variety of facial expressions we use in daily life, research on facial expressions has so far mostly focused on the emotional aspect. Consequently, most databases of facial expressions available to the research community also include only emotional expressions, neglecting the largely unexplored aspect of conversational expressions. To fill this gap, we present the MPI facial expression database, which contains a large variety of natural emotional and conversational expressions. The database contains 55 different facial expressions performed by 19 German participants. Expressions were elicited with the help of a method-acting protocol, which guarantees both well-defined and natural facial expressions. The method-acting protocol was based on every-day scenarios, which are used to define the necessary context information for each expression. All facial expressions are available in three repetitions, in two intensities, as well as from three different camera angles. A detailed frame annotation is provided, from which a dynamic and a static version of the database have been created. In addition to describing the database in detail, we also present the results of an experiment with two conditions that serve to validate the context scenarios as well as the naturalness and recognizability of the video sequences. Our results provide clear evidence that conversational expressions can be recognized surprisingly well from visual information alone. The MPI facial expression database will enable researchers from different research fields (including the perceptual and cognitive sciences, but also affective computing, as well as computer vision to investigate the processing of a wider range of natural

    To evaluate the relationship between facial growth pattern and electromyography (EMG) of facial muscles: anterior temporalis, masseter, buccinators, orbicularis oris, mentalis and anterior digastric. The sample consisted of 77 subjects aged between 18-28 years (mean age 21.10±2.03), with dental Class I relationship, normal overjet and overbite, balanced facial profile, no signs of temporomandibular disorders, and no previous orthodontic treatment. Facial growth pattern was determined on the lateral cephalograms according to the Björk sum (sum of the N-S-Ar, S-Ar-Go, and Ar-Go-Me angles) dividing the sample into three groups: horizontal facial pattern group (24 subjects), normal facial pattern group (41 subjects), and vertical facial pattern group (12 subjects). The EMG of anterior temporalis, masseter, buccinator, orbicularis oris, mentalis and anterior digastric muscles were examined for each patient in the rest position and in functional positions (central maximum intercuspation, chewing on right side, chewing on left side and swallowing). Mean values and standard deviation of EMG were obtained and compared between the three groups. At rest, the EMG of the masseter, orbicularis oris and anterior digastric were higher in the vertical facial pattern group compared with the other two groups, with a moderate positive correlation between the EMG of these muscles and the Björk sum (Pmuscles (Pmuscle activity and facial growth pattern. The findings suggest that the activity of masticatory and perioral muscles could play a role in the direction of the facial growth. Copyright © 2015 CEO. Published by Elsevier Masson SAS.

    Full Text Available INTRODUCTION: In orthodontics, determining the facial type is a key element in the prescription of a correct diagnosis. In the early days of our specialty, observation and measurement of craniofacial structures were done directly on the face, in photographs or plaster casts. With the development of radiographic methods, cephalometric analysis replaced the direct facial analysis. Seeking to validate the analysis of facial soft tissues, this work compares two different methods used to determining the facial types, the anthropometric and the cephalometric methods. METHODS: The sample consisted of sixty-four Brazilian individuals, adults, Caucasian, of both genders, who agreed to participate in this research. All individuals had lateral cephalograms and facial frontal photographs. The facial types were determined by the Vert Index (cephalometric and the Facial Index (photographs. RESULTS: The agreement analysis (Kappa, made for both types of analysis, found an agreement of 76.5%. CONCLUSIONS: We concluded that the Facial Index can be used as an adjunct to orthodontic diagnosis, or as an alternative method for pre-selection of a sample, avoiding that research subjects have to undergo unnecessary tests.INTRODUÇÃO: em Ortodontia, a determinação do tipo facial é um elemento-chave na prescrição de um diagnóstico correto.

    2017-02-06

    Human parental care relies heavily on the ability to monitor and respond to a child's affective states. The current study examined pupil diameter as a potential physiological index of mothers' affective response to infant facial expressions. Pupillary time-series were measured from 86 mothers of young infants in response to an array of photographic infant faces falling into four emotive categories based on valence (positive vs. negative) and arousal (mild vs. strong). Pupil dilation was highly sensitive to the valence of facial expressions, being larger for negative vs. positive facial expressions. A separate control experiment with luminance-matched non-face stimuli indicated that the valence effect was specific to facial expressions and cannot be explained by luminance confounds. Pupil response was not sensitive to the arousal level of facial expressions. The results show the feasibility of using pupil diameter as a marker of mothers' affective responses to ecologically valid infant stimuli and point to a particularly prompt maternal response to infant distress cues.

  6. Perception of health from facial cues

    2016-01-01

    Impressions of health are integral to social interactions, yet poorly understood. A review of the literature reveals multiple facial characteristics that potentially act as cues to health judgements. The cues vary in their stability across time: structural shape cues including symmetry and sexual dimorphism alter slowly across the lifespan and have been found to have weak links to actual health, but show inconsistent effects on perceived health. Facial adiposity changes over a medium time course and is associated with both perceived and actual health. Skin colour alters over a short time and has strong effects on perceived health, yet links to health outcomes have barely been evaluated. Reviewing suggested an additional influence of demeanour as a perceptual cue to health. We, therefore, investigated the association of health judgements with multiple facial cues measured objectively from two-dimensional and three-dimensional facial images. We found evidence for independent contributions of face shape and skin colour cues to perceived health. Our empirical findings: (i) reinforce the role of skin yellowness; (ii) demonstrate the utility of global face shape measures of adiposity; and (iii) emphasize the role of affect in facial images with nominally neutral expression in impressions of health.

    Many investigators have proved that Dead Sea salt and mud are useful in treating skin disorders and skin diseases. Therefore, the black mud has been extensively used as a base for the preparation of soaps, creams, and unguents for skin care. This study concerns a facial mask made mainly of Dead Sea mud. The effects of temperature and shearing conditions on the rheological behavior of the facial mask were investigated. The mud facial mask exhibited a shear thinning behavior with a yield stress. It was found that the apparent viscosity of the mask has a strong dependence on the shear rate as well as on the temperature. The facial mask exhibited a maximum yield stress and very shear thinning behavior at 40 degrees C, which is attributed to the gelatinization of the polysaccharide used to stabilize the mud particles. On the other hand, the mud mask exhibited a time-independent behavior at low temperatures and shear rates and changed to a thixotropic behavior upon increasing both the temperature and the shear rate. The shear thinning and thixotropic behaviors have a significant importance in the ability of the facial mask to spread on the skin: the Dead Sea mud mask can break down for easy spreading, and the applied film can gain viscosity instantaneously to resist running. Moreover, particle sedimentation, which in this case would negatively affect consumer acceptance of the product, occurs slowly due to high viscosity at rest conditions.

  8. Stability of Facial Affective Expressions in Schizophrenia

    2012-01-01

    Full Text Available Thirty-two videorecorded interviews were conducted by two interviewers with eight patients diagnosed with schizophrenia. Each patient was interviewed four times: three weekly interviews by the first interviewer and one additional interview by the second interviewer. 64 selected sequences where the patients were speaking about psychotic experiences were scored for facial affective behaviour with Emotion Facial Action Coding System (EMFACS. In accordance with previous research, the results show that patients diagnosed with schizophrenia express negative facial affectivity. Facial affective behaviour seems not to be dependent on temporality, since within-subjects ANOVA revealed no substantial changes in the amount of affects displayed across the weekly interview occasions. Whereas previous findings found contempt to be the most frequent affect in patients, in the present material disgust was as common, but depended on the interviewer. The results suggest that facial affectivity in these patients is primarily dominated by the negative emotions of disgust and, to a lesser extent, contempt and implies that this seems to be a fairly stable feature.

    Full Text Available Prior studies have shown that performance on standardized measures of memory in children with autism spectrum disorder (ASD is substantially reduced in comparison to matched typically developing controls (TDC. Given reported deficits in face processing in autism, the current study compared performance on an immediate and delayed facial memory task for individuals with ASD and TDC. In addition, we examined volumetric differences in classic facial memory regions of interest (ROI between the two groups, including the fusiform, amygdala, and hippocampus. We then explored the relationship between ROI volume and facial memory performance. We found larger volumes in the autism group in the left amygdala and left hippocampus compared to TDC. In contrast, TDC had larger left fusiform gyrus volumes when compared with ASD. Interestingly, we also found significant negative correlations between delayed facial memory performance and volume of the left and right fusiform and the left hippocampus for the ASD group but not for TDC. The possibility of larger fusiform volume as a marker of abnormal connectivity and decreased facial memory is discussed.

    Full Text Available The aim of the present study was to identify risk factors for facial fractures in patients treated in the emergency department of a hospital. The medical charts of 1121 patients treated in an emergency ward over a three-year period were analyzed. The independent variables were gender, age, place of residence (urban or rural area and type of accident. The dependent variables were fractured mandible, zygoma, maxilla, nasal bone and more than one fractured facial bone. Statistical analysis was performed using the chi-square test (a < 0.05, univariate and multivariate Poisson distributions and the logistic regression analysis (p < 0.20. Maxillofacial trauma was recorded in 790 charts (70.5%, with 393 (35.1% charts reporting facial fractures. Motorcycle accidents were found to be the main risk factor for mandibular fractures (PR = 1.576, CI = 1.402-1.772 and simultaneous fractures of more than one facial bone (OR = 4.625, CI = 1.888-11.329 as well as the only risk factor for maxillary bone fractures (OR = 11.032, CI = 5.294-22.989. Fractures of the zygomatic and nasal bones were mainly associated with accidents involving animals (PR = 1.206, CI = 1.104-1.317 and sports (OR = 8.710, CI = 4.006-18.936, respectively. The determinant for the majority of facial fractures was motorcycle accidents, followed by accidents involving animals and sports.

  11. Facial Edema Evaluation Using Digital Image Processing

    2013-01-01

    Full Text Available The main objective of the facial edema evaluation is providing the needed information to determine the effectiveness of the anti-inflammatory drugs in development. This paper presents a system that measures the four main variables present in facial edemas: trismus, blush (coloration, temperature, and inflammation. Measurements are obtained by using image processing and the combination of different devices such as a projector, a PC, a digital camera, a thermographic camera, and a cephalostat. Data analysis and processing are performed using MATLAB. Facial inflammation is measured by comparing three-dimensional reconstructions of inflammatory variations using the fringe projection technique. Trismus is measured by converting pixels to centimeters in a digitally obtained image of an open mouth. Blushing changes are measured by obtaining and comparing the RGB histograms from facial edema images at different times. Finally, temperature changes are measured using a thermographic camera. Some tests using controlled measurements of every variable are presented in this paper. The results allow evaluating the measurement system before its use in a real test, using the pain model approved by the US Food and Drug Administration (FDA, which consists in extracting the third molar to generate the facial edema.

    To evaluate the usefulness of 3 dimensional volume MR imaging technique for demonstrating the facial nerves and to describe MR findings in facial palsy patients and evaluate the significance of facial nerve enhancement. We reviewed the MR images of facial nerves obtained with 3 dimensional volume imaging technique before and after intravenous administration of Gadopentetate dimeglumine in 13 cases who had facial paralysis and 33 cases who had no facial palsy. And we analyzed the detectability of ananatomical segments of intratemporal facial nerves and facial nerve enhancement. When the 3 dimensional volume MR images of 46 nerves were analyzed subjectively, the nerve courses of 43(93%) of 46 nerves were effectively demonstrated on 3 dimensional volume MR images. Internal acoustic canal portions and geniculate ganglion of facial nerve were well visualized on axial images and tympanic and mastoid segments were well depicted on oblique sagittal images. 10 of 13 patients(77%) were visibly enhanced along at least one segment of the facial nerve with swelling or thickening, and nerves of 8 of normal 33 cases(24%) were enhanced without thickening or swelling. MR findings of facial nerve parelysis is asymmetrical thickening of facial nerve with contrast enhancement. The 3 dimensional volume MR imaging technique should be a useful study for the evaluation of intratemporal facial nerve disease.

    Full Text Available En comparación con las numerosas investigaciones centradas en los factores de vulnerabilidad cognitiva que subyacen en el inicio y el desarrollo del trastorno depresivo mayor, los estudios que investigan el procesamiento disfuncional de la información emocional en el trastorno bipolar siguen siendo escasos. Por ello, el presente estudio experimental ha analizado la naturaleza y el curso temporal de los sesgos atencionales en pacientes depresivos con trastorno bipolar. Un total de catorce pacientes deprimidos con Trastorno Bipolar I (TB y catorce participantes controles no deprimidos (CN, emparejados en edad, sexo y nivel educativo, realizaron una modificación emocional de la tarea de señalización espacial. Las señales consistían en expresiones faciales de enfado, neutrales y positivas presentadas durante 200 y 1.000 ms. Los pacientes con TB mostraron un mayor efecto de validación de las señales en las caras de enfado y presentaron más dificultades a la hora de desvincular la atención de las expresiones faciales de enfado y de alegría en comparación con los participantes CN, que por el contrario, demostraron un «sesgo protector» distanciado de la información negativa. Este patrón diferenciado de procesamiento atencional solo se halló en la fase inicial del procesamiento de la información en una presentación de 200 ms de duración. Estos resultados demuestran la existencia de déficits en las fases iniciales del procesamiento atencional de la información emocional en pacientes deprimidos bipolares en comparación con los controles sanos.

    Aim of the present observational single center study was to objectively assess facial function in patients with idiopathic facial palsy with a new computer-based system that automatically recognizes action units (AUs) defined by the Facial Action Coding System (FACS). Still photographs using posed facial expressions of 28 healthy subjects and of 299 patients with acute facial palsy were automatically analyzed for bilateral AU expression profiles. All palsies were graded with the House-Brackmann (HB) grading system and with the Stennert Index (SI). Changes of the AU profiles during follow-up were analyzed for 77 patients. The initial HB grading of all patients was 3.3 ± 1.2. SI at rest was 1.86 ± 1.3 and during motion 3.79 ± 4.3. Healthy subjects showed a significant AU asymmetry score of 21 ± 11 % and there was no significant difference to patients (p = 0.128). At initial examination of patients, the number of activated AUs was significantly lower on the paralyzed side than on the healthy side (p facial grading is worthwhile: automated FACS delivers fast and objective global and regional data on facial motor function for use in clinical routine and clinical trials.

    Spectropolarimetric imaging can provide useful discriminating information for human face recognition that cannot be obtained by other imaging methods. This paper examines the ability of face recognition by using spectropolarimetric images. The Spectropolarimetric images were collected by using a CCD camera equipped with a liquid crystal tunable filter, which could capture 32 bands of images over the visible and near-infrared light (0.4μm-0.72μm). Since polarization techniques have better contrast mechanisms for tissue imaging and spectroscopy, and can also provide additional information about the structure of tissues, it is expected that better discriminate performance can be obtained by using polarimetric and spectral information than just using spectral information. An algorithm for facial characteristics analysis is presented to exploit only the spectropolarimetric information from different types of facial tissues. Experiments demonstrate that the proposed algorithm can distinguish efficiently the different facial tissues.

    Full Text Available This paper presents a hybrid method for synthesizing natural animation of facial expression with data from motion capture. The captured expression was transferred from the space of source performance to that of a 3D target face using an accurate mapping process in order to realize the reuse of motion data. The transferred animation was then applied to synthesize the expression of the target model through a framework of two-stage deformation. A local deformation technique preliminarily considered a set of neighbor feature points for every vertex and their impact on the vertex. Furthermore, the global deformation was exploited to ensure the smoothness of the whole facial mesh. The experimental results show our hybrid mesh deformation strategy was effective, which could animate different target face without complicated manual efforts required by most of facial animation approaches.

    Facial pain in lung cancer patients may be secondary to metastatic disease to the brain or skull base. Since 1983 there have been 19 published reports of hemi-facial pain as a non-metastatic complication of lung carcinoma. This report describes an additional case in whom unilateral face pain preceded the diagnosis of lung cancer by 9 months. A clinical diagnosis of trigeminal neuralgia was made after a normal brain CT scan. Later on the patient complained of global lethargy, weight loss and haemoptysis. A chest X-ray disclosed a 6 cm right hilar mass that was further defined with a whole body CT scan. The neural mechanism of the unilateral facial pain is discussed and the literature reviewed. 14 refs., 1 tab.

  8. Lagophthalmos after facial palsy: current therapeutic options.

    Vásquez, Luz María; Medel, Ramón

    2014-01-01

    As the facial nerve carries sensory, motor and parasympathetic fibres involved in facial muscle innervation, facial palsy results in functional and cosmetic impairment. It can result from a wide variety of causes like infectious processes, trauma, neoplasms, autoimmune diseases, and most commonly Bell's palsy, but it can also be of iatrogenic origin. The main ophthalmic sequel is lagophthalmos. The increased surface exposure increases the risk of keratitis, corneal ulceration, and potentially loss of vision. Treatment options are wide; some are temporary, some permanent. In addition to gold standard and traditional therapies and procedures, new options are being proposed aiming to improve not only lagophthalmos but also the quality of life of these patients. © 2014 S.

    Facial locoregional anesthetics (ALR) with nervous blocks are simple and reliable to perform, need little technical resources with a very low iatrogenic risk. These blocks allow anesthesia without deforming wound banks using the same materials as usual local anesthetic procedures. Three principal nervous blocks, in a straight line along the vertical pupil axis, allow managing - even extensive - facial wounds. Few side effects may occur which can be easily prevented. It is a good alternative to local anesthetic for the treatment of extensive and deep areas which is performed with a lower number of injections and a high rate of success. These techniques are easy to learn and practise. These anesthetic techniques allow a nice treatment of different kinds of facial wounds from simple suture to flaps.

    Sickle cell disease (SCD) is characterized as a chronic hemolytic anemia with vaso-occlusive crises that result in multisystem organ damage. Bone marrow is one of the more common sites of these crises, presumably due to marrow hypercellularity that impairs blood flow- leading to regional hypoxia and subsequent infarction. Infarcts of facial bones are considered an uncommon complication of SCD. When infarcts occur in facial bones, the mandible and orbital bones are the most commonly affected. Overall, the clinical presentation of facial bone infarctions may mimic an infectious process, such as cellulitis, an abscess, or, more commonly, osteomyelitis. The purpose of this paper was to present the case of a patient with a confluence of symptoms in the face as a result of her sickle cell disease.

    Said, Christopher P; Todorov, Alexander

    2011-09-01

    Previous research has identified facial averageness and sexual dimorphism as important factors in facial attractiveness. The averageness and sexual dimorphism accounts provide important first steps in understanding what makes faces attractive, and should be valued for their parsimony. However, we show that they explain relatively little of the variance in facial attractiveness, particularly for male faces. As an alternative to these accounts, we built a regression model that defines attractiveness as a function of a face's position in a multidimensional face space. The model provides much more predictive power than the averageness and sexual dimorphism accounts and reveals previously unreported components of attractiveness. The model shows that averageness is attractive in some dimensions but not in others and resolves previous contradictory reports about the effects of sexual dimorphism on the attractiveness of male faces.

    Approximately 1% of all live births exhibit a minor or major congenital anomaly. Of these approximately one-third display craniofacial abnormalities which are a significant cause of infant mortality and dramatically affect national health care budgets. To date, more than 700 distinct craniofacial syndromes have been described and in this review, we discuss the etiology, pathogenesis and management of facial dysostoses with a particular emphasis on Treacher Collins, Nager and Miller syndromes. As we continue to develop and improve medical and surgical care for the management of individual conditions, it is essential at the same time to better characterize their etiology and pathogenesis. Here we describe recent advances in our understanding of the development of facial dysostosis with a view towards early in utero identification and intervention which could minimize the manifestation of anomalies prior to birth. The ultimate management for any craniofacial anomaly however, would be prevention and we discuss this possibility in relation to facial dysostosis.

    Nowadays, documenting the face appearance through imaging is prevalent in skin research, therefore detection and quantitative assessment of the degree of facial wrinkling is a useful tool for establishing an objective baseline and for communicating benefits to facial appearance due to cosmetic procedures or product applications. In this work, an algorithm for automatic detection of facial wrinkles is developed, based on estimating the orientation and the frequency of elongated features apparent on faces. By over-filtering the skin texture image with finely tuned oriented Gabor filters, an enhanced skin image is created. The wrinkles are detected by adaptively thresholding the enhanced image, and the degree of wrinkling is estimated based on the magnitude of the filter responses. The algorithm is tested against a clinically scored set of images of periorbital lines of different severity and we find that the proposed computational assessment correlates well with the corresponding clinical scores.

    Full Text Available We have previously demonstrated a neuroprotective mechanism of FMN (facial motoneuron survival after facial nerve axotomy that is dependent on CD4+ Th2 cell interaction with peripheral antigen-presenting cells, as well as CNS (central nervous system-resident microglia. PACAP (pituitary adenylate cyclase-activating polypeptide is expressed by injured FMN and increases Th2-associated chemokine expression in cultured murine microglia. Collectively, these results suggest a model involving CD4+ Th2 cell migration to the facial motor nucleus after injury via microglial expression of Th2-associated chemokines. However, to respond to Th2-associated chemokines, Th2 cells must express the appropriate Th2-associated chemokine receptors. In the present study, we tested the hypothesis that Th2-associated chemokine receptors increase in the facial motor nucleus after facial nerve axotomy at timepoints consistent with significant T-cell infiltration. Microarray analysis of Th2-associated chemokine receptors was followed up with real-time PCR for CCR3, which indicated that facial nerve injury increases CCR3 mRNA levels in mouse facial motor nucleus. Unexpectedly, quantitative- and co-immunofluorescence revealed increased CCR3 expression localizing to FMN in the facial motor nucleus after facial nerve axotomy. Compared with WT (wild-type, a significant decrease in FMN survival 4 weeks after axotomy was observed in CCR3−/− mice. Additionally, compared with WT, a significant decrease in FMN survival 4 weeks after axotomy was observed in Rag2−/− (recombination activating gene-2-deficient mice adoptively transferred CD4+ T-cells isolated from CCR3−/− mice, but not in CCR3−/− mice adoptively transferred CD4+ T-cells derived from WT mice. These results provide a basis for further investigation into the co-operation between CD4+ T-cell- and CCR3-mediated neuroprotection after FMN injury.

    This study was undertaken to identify premotor neurons in the nucleus tractus solitarii (NTS) serving as relay neurons between the sensory trigeminal complex (STC) and the facial motor nucleus in rats. Trigemino-solitarii connections were first investigated following injections of anterograde and/or retrograde (biotinylated dextran amine, biocytin, or gold-HRP) tracers in STC or NTS. Trigemino-solitarii neurons were abundant in the ventral and dorsal parts of the STC and of moderate density in its intermediate part. They project throughout the entire rostrocaudal extent of the NTS with a strong lateral preponderance. Solitarii-trigeminal neurons were observed mostly in the rostral and rostrolateral NTS. They mainly project to the ventral and dorsal parts of the spinal trigeminal nucleus but not to the principal nucleus. Additional neurons located in the middle NTS were found to project exclusively to the spinal trigeminal nucleus pars caudalis. No solitarii-trigeminal cells were observed in the caudal NTS. In addition, evidence was obtained of NTS retrogradely labeled neurons contacted by anterogradely labeled trigeminal terminals. Second, solitarii-facial projections were analyzed following injections of anterograde and retrograde tracers into the NTS and the facial nucleus, respectively. NTS neurons, except those of the rostrolateral part, reached the dorsal aspect of the facial nucleus. Finally, simultaneous injections of anterograde tracer in the STC and retrograde tracer in the facial nucleus gave retrogradely labeled neurons in the NTS receiving contacts from anterogradely labeled trigeminal boutons. Thus, the present data demonstrate for the first time the existence of a trigemino-solitarii-facial pathway. This could account for the involvement of the NTS in the control of orofacial motor behaviors.

  20. Cognitive factors associated with facial pain.

    Most well-accepted etiological models of facial pain (e.g., temporomandibular disorders and headache) implicate emotional distress as an important factor in the development and maintenance of pain. Data exists to support the notion that some facial pain sufferers are more emotionally distressed than no pain controls. However, many of these dependent measures of emotional distress are either lengthy assessment batteries, lack clear cut psychotherapeutic treatment implications, or focus exclusively on pain related sequela. As cognitive-behavioral interventions become more integrated into the treatment of chronic pain conditions, including various facial pain conditions, it becomes more imperative that the tools used to assess psychological functioning provide the clinician with specific cognitive/behavioral targets for change. The purpose of this study was to assess the degree to which symptomatic treatment seeking facial pain sufferers (N = 25), symptomatic non-treatment seeking facial pain sufferers (N = 48), and healthy pain-free controls (N = 70) differed on the Rational Beliefs Inventory (RBI). The RBI is a reliable, valid questionnaire assessing rational beliefs that are operationalized within a Rational Emotive Therapy (RET) framework. RET is a cognitive-behavioral treatment paradigm that focuses on how an individual's maladaptive cognitive errors or distortions exacerbate emotional distress. Group differences were assessed using a oneway Analysis of Covariance (ANCOVA) with the total RBI score serving as the dependent measure, and a Multivariate Analysis of Covariance (MANCOVA) using individual RBI belief subscales as dependent measures. These results indicated that groups differed significantly on the total score and several of the individual belief subscales. These findings indicated that facial pain sufferers generally hold maladaptive beliefs that may be of clinical significance for cognitive/behavioral treatment approaches.

    Full Text Available In this paper, a method for localization and extraction of faces and characteristic facial features such as eyes, mouth and face boundaries from color image data is proposed. This approach exploits color properties of human skin to localize image regions – face candidates. The facial features extraction is performed only on preselected face-candidate regions. Likewise, for eyes and mouth localization color information and local contrast around eyes are used. The ellipse of face boundary is determined using gradient image and Hough transform. Algorithm was tested on image database Feret.

    Factors that are important to successful face recognition, such as features, configuration, and pigmentation/reflectance, are all subject to change when a face has been engraved with ink markings. Here we show that the application of facial tattoos, in the form of spiral patterns (typically associated with the Maori tradition of a Moko), disrupts face recognition to a similar extent as face inversion, with recognition accuracy little better than chance performance (2AFC). These results indicate that facial tattoos can severely disrupt our ability to recognise a face that previously did not have the pattern.

    Coia, John E; Ritchie, Lisa; Fry, Carole

    Infectious microorganisms can be transmitted by various routes. Respiratory and facial protection is needed to prevent infection with organisms that are usually transmitted through the droplet/airborne route, or when airborne particles have been artificially created, for example during aerosol-generating procedures. Recent experiences with severe acute respiratory syndrome and pandemic (H1N1) influenza in 2009 highlighted that health professionals may have difficulty in choosing the correct facial and respiratory protection. The Scientific Development Committee of the Healthcare Infection HealtSociety established a working group to develop guidance addressing this issue.

    PFAPA (periodic fever, apthous stomatitis, pharyngitis, cervical adenitis) is a rare condition of unknown cause affecting children. Although the exact etiology is unknown, inflammatory, immunological or genetic causes have been suggested. The diagnosis is made by exclusion of other causes of periodic fever. Although management is essentially symptomatic, single corticosteroid dose, tonsillectomy and Cimetidine has been shown to be associated with resolution of symptoms. Although abdominal pain and genital ulcers have been reported in association with PFAPA, unilateral transient facial swelling has not been previously reported. The authors present a hitherto unreported association of PFAPA with recurrent episodes of unilateral facial swelling.

    Peripheral facial nerve palsy (FNP) is a mononeuropathy that affects the peripheral part of the facial nerve. Primary causes of peripheral FNP remain largely unknown, but detectable causes include systemic infections (viral and others), trauma, ischemia, tumor, and extrinsic compression. Peripheral FNP in relation to extrinsic compression has rarely been described in case reports. Here, we report a case of a 71-year-old man who was diagnosed with peripheral FNP following endoscopic submucosal dissection. This case is the first report of the development of peripheral FNP in a patient undergoing therapeutic endoscopy. We emphasize the fact that physicians should be attentive to the development of peripheral FNP following therapeutic endoscopy.

    The preoperative assessment of the eye in facial paralysis is a critical component of surgical management. The degree of facial nerve paralysis, lacrimal secretion, corneal sensation, and lower eyelid position must be assessed accurately. Upper eyelid loading procedures are standard management of lagophthalmos. Lower eyelid tightening repositions the lower eyelid and helps maintain the aqueous tear film. Eyelid reanimation allows an aesthetic symmetry with blinking and restores protective functions vital to ocular preservation. Patients often have multiple nervous deficits, including corneal anesthesia. Other procedures include tarsorrhaphy, spring implantation, and temporalis muscle transposition; associated complications have rendered them nearly obsolete.

Patients with chronic pain who had been performed previous implant surgery or related surgical intervention sometimes accompany with psychological problem and difficult to adequately manage. According to the International Classification of Headache Disorders (ICHD 3rd eds, Cepalagia 2013, painful neuropathies and other facial pains are subdivided into the 12 subcategories; 13.1. Trigeminal neuralgia; 13.2 Glossopharyngeal neuralgia; 13.3 Nervus intermedius (facial nerve neuralgia; 13.4 Occipital neuralgia; 13.5 Optic neuritis; 13.6 Headache attributed to ischaemic ocular motor nerve palsy; 13.7 Tolosa-Hunt syndrome; 13.8 Paratrigeminal oculo-sympathetic (Raeder’s syndrome; 13.9 Recurrent painful ophthalmoplegic neuropathy; 13.10 Burning Mouth Syndrome (BMS; 13.11 Persistent Idiopathic Facial Pain (PIFP; 13.12 Central neuropathic pain. Chronic orofacial pain after dental implant surgery can be largely into the two main categories that can be frequently encountered in clinical basis ; 1 Neuropathic pain, 2 Idiopathic pain. If there is no direct evidence of the nerve injury related with the implant surgery, the clinician need to consider the central cause of pain instead of the peripheral cause of the pain. There might be several possibilities; 1 Anaesthesia dolorosa, 2 Central post-stroke pain, 3 Facial pain attributed to multiple sclerosis, 4 Persistent idiopathic facial pain (PIFP, 5 Burning mouth syndrome. In this presentation, Persistent idiopathic facial pain (PIFP, the disease entity that can be frequently encountered in the clinic would be discussed.

    2014-08-01

    Background Facial nerve paralysis in a patient with a salivary gland mass usually denotes malignancy. However, facial paralysis can also be caused by benign salivary gland tumors. Methods We present a case of facial nerve paralysis due to a benign salivary gland tumor that had the imaging characteristics of an intraparotid facial nerve schwannoma. Results The patient presented to our clinic 4 years after the onset of facial nerve paralysis initially diagnosed as Bell palsy. Computed tomography demonstrated filling and erosion of the stylomastoid foramen with a mass on the facial nerve. Postoperative histopathology showed the presence of a pleomorphic adenoma. Facial paralysis was thought to be caused by extrinsic nerve compression. Conclusions This case illustrates the difficulty of accurate preoperative diagnosis of a parotid gland mass and reinforces the concept that facial nerve paralysis in the context of salivary gland tumors may not always indicate malignancy.

  3. Holistic gaze strategy to categorize facial expression of varying intensities.

    Directory of Open Access Journals (Sweden)

    Kun Guo

    Full Text Available Using faces representing exaggerated emotional expressions, recent behaviour and eye-tracking studies have suggested a dominant role of individual facial features in transmitting diagnostic cues for decoding facial expressions. Considering that in everyday life we frequently view low-intensity expressive faces in which local facial cues are more ambiguous, we probably need to combine expressive cues from more than one facial feature to reliably decode naturalistic facial affects. In this study we applied a morphing technique to systematically vary intensities of six basic facial expressions of emotion, and employed a self-paced expression categorization task to measure participants' categorization performance and associated gaze patterns. The analysis of pooled data from all expressions showed that increasing expression intensity would improve categorization accuracy, shorten reaction time and reduce number of fixations directed at faces. The proportion of fixations and viewing time directed at internal facial features (eyes, nose and mouth region, however, was not affected by varying levels of intensity. Further comparison between individual facial expressions revealed that although proportional gaze allocation at individual facial features was quantitatively modulated by the viewed expressions, the overall gaze distribution in face viewing was qualitatively similar across different facial expressions and different intensities. It seems that we adopt a holistic viewing strategy to extract expressive cues from all internal facial features in processing of naturalistic facial expressions.

  4. Facial animation on an anatomy-based hierarchical face model

    Science.gov (United States)

    Zhang, Yu; Prakash, Edmond C.; Sung, Eric

    2003-04-01

    In this paper we propose a new hierarchical 3D facial model based on anatomical knowledge that provides high fidelity for realistic facial expression animation. Like real human face, the facial model has a hierarchical biomechanical structure, incorporating a physically-based approximation to facial skin tissue, a set of anatomically-motivated facial muscle actuators and underlying skull structure. The deformable skin model has multi-layer structure to approximate different types of soft tissue. It takes into account the nonlinear stress-strain relationship of the skin and the fact that soft tissue is almost incompressible. Different types of muscle models have been developed to simulate distribution of the muscle force on the skin due to muscle contraction. By the presence of the skull model, our facial model takes advantage of both more accurate facial deformation and the consideration of facial anatomy during the interactive definition of facial muscles. Under the muscular force, the deformation of the facial skin is evaluated using numerical integration of the governing dynamic equations. The dynamic facial animation algorithm runs at interactive rate with flexible and realistic facial expressions to be generated.

    2016-01-01

    Various models have been proposed to increase understanding of the cognitive basis of facial emotions. Despite those efforts, interactions between facial emotions have received minimal attention. If collective behaviours relating to each facial emotion in the comprehensive cognitive system could be assumed, specific facial emotion relationship patterns might emerge. In this study, we demonstrate that the frameworks of complex networks can effectively capture those patterns. We generate 81 facial emotion images (6 prototypes and 75 morphs) and then ask participants to rate degrees of similarity in 3240 facial emotion pairs in a paired comparison task. A facial emotion network constructed on the basis of similarity clearly forms a small-world network, which features an extremely short average network distance and close connectivity. Further, even if two facial emotions have opposing valences, they are connected within only two steps. In addition, we show that intermediary morphs are crucial for maintaining full network integration, whereas prototypes are not at all important. These results suggest the existence of collective behaviours in the cognitive systems of facial emotions and also describe why people can efficiently recognize facial emotions in terms of information transmission and propagation. For comparison, we construct three simulated networks--one based on the categorical model, one based on the dimensional model, and one random network. The results reveal that small-world connectivity in facial emotion networks is apparently different from those networks, suggesting that a small-world network is the most suitable model for capturing the cognitive basis of facial emotions.

    BACKGROUND: Studies have demonstrated that damaged facial nerves synthesize prosaposin to promote repair of facial neurons.OBJECTIVE: To observe time-course changes of prosaposin expression in the facial nerve nucleus of Sprague Dawley rats following facial nerve transection and repair.DESIGN, TIME AND SETTING: A randomized control neuropathological animal experiment was performed in Chongqing Medical University between March 2007 and September 2008.MATERIALS: A total of 48 adult, male, Sprague Dawley rats were selected and randomly divided into transection and transection + end-to-end anastomosis groups (n =24). Rabbit anti-rat prosaposin antibody, instant SABC immunohistochemical kit, and antibody dilution solution were purchased from Wuhan Uscn Science Co., Ltd., China.METHODS: In the transection group, the nerve trunk of the distal retroauricular branch of the left facial nerves was ligated in Sprague Dawley rats, and a 5-mm nerve trunk at the distal end of the ligation site was removed. In the transection + end-to-end anastomosis group, epineurial anastomosis was performed immediately following transection of the left facial nerves. The right facial nerves in the two groups sewed as the normal control group.MAIN OUTCOME MEASURES: The number of prosaposin-positive neurons, as well as intensity of immunostaining in facial nerve nucleus, following transection and end-to-end anastomosis were determined by immunohistochemistry at 1,3, 7, 14, 21, and 35 days after injury.RESULTS: Transection group: transection of facial nerves resulted in increased number of prosaposin-positive neurons and immunoreactivity intensity in the facial nucleus on day 1. These values significantly increased by day 3. Expression was greater than in the control side. The peak of the reduction was reached at 7 days post-surgery. Transection + end-to-end anastomosis group: the number of prosaposin-positive neurons and immunoreactivity intensity was reduced in the facial nerve nucleus following

  11. Facial age affects emotional expression decoding

    Full Text Available Facial expressions convey important information on emotional states of our interaction partners. However, in interactions between younger and older adults, there is evidence for a reduced ability to accurately decode emotional facial expressions.Previous studies have often followed up this phenomenon by examining the effect of the observers’ age. However, decoding emotional faces is also likely to be influenced by stimulus features, and age-related changes in the face such as wrinkles and folds may render facial expressions of older adults harder to decode. In this paper, we review theoretical frameworks and empirical findings on age effects on decoding emotional expressions, with an emphasis on age-of-face effects. We conclude that the age of the face plays an important role for facial expression decoding. Lower expressivity, age-related changes in the face, less elaborated emotion schemas for older faces, negative attitudes toward older adults, and different visual scan patterns and neural processing of older than younger faces may lower decoding accuracy for older faces. Furthermore, age-related stereotypes and age-related changes in the face may bias the attribution of specific emotions such as sadness to older faces.

    Facial animation surgery with neuromuscular transplants has become a standard procedure for the treatment of facial palsies. However, the forehead, periocular complex, nasal base area, and inferior lip are secondary sites that also need to be considered in the complete rehabilitation of a flaccid facial palsy. A total of 136 ancillary procedures were performed in 49 patients between 2003 and 2013 and consisted of eyebrow suspensions (11), upper eyelid loading with a platinum chain (39), inferior palpebral suspension with fascia lata (22), nasal base suspension with fascia lata (26), and botulinum toxin injection (38). Cosmetic results were good and excellent in 30.7% and 63.2% of the procedures, respectively. Functionally, periocular complex rehabilitation and nasal base suspension led to excellent improvements in function in 87.2% and 73.1% of the patients, respectively. The use of ancillary procedures can improve the functional and esthetic results of facial animation surgery. Copyright © 2014 American Association of Oral and Maxillofacial Surgeons.

    Full Text Available There is a wide debate on the mental state of doubt/uncertainty; one wonders whether it is a predominantly cognitive or emotional state of mind and whether typical facial expressions communicate doubt/uncertainty. To this purpose,through a role playing procedure, a large sample of expressions were collected and afterwards evaluated through a combination of encoding and decoding procedures,including also FACS (Facial Action Coding System analysis. The results have partially confirmed our hypothesis, identifying two typical facial expressions of doubt/uncertainty, which share the same facial actions in the inferior part of the face and show differential facial actions in the upper face.

  19. Facial identity and facial expression are initially integrated at visual perceptual stages of face processing.

    It is frequently assumed that facial identity and facial expression are analysed in functionally and anatomically distinct streams within the core visual face processing system. To investigate whether expression and identity interact during the visual processing of faces, we employed a sequential matching procedure where participants compared either the identity or the expression of two successively presented faces, and ignored the other irrelevant dimension. Repetitions versus changes of facial identity and expression were varied independently across trials, and event-related potentials (ERPs) were recorded during task performance. Irrelevant facial identity and irrelevant expression both interfered with performance in the expression and identity matching tasks. These symmetrical interference effects show that neither identity nor expression can be selectively ignored during face matching, and suggest that they are not processed independently. N250r components to identity repetitions that reflect identity matching mechanisms in face-selective visual cortex were delayed and attenuated when there was an expression change, demonstrating that facial expression interferes with visual identity matching. These findings provide new evidence for interactions between facial identity and expression within the core visual processing system, and question the hypothesis that these two attributes are processed independently.

    Virtual reality is rapidly evolving into a pragmatically usable technology for mental health (MH) applications. As the underlying enabling technologies continue to evolve and allow us to design more useful and usable structural virtual environments (VEs), the next important challenge will involve populating these environments with virtual representations of humans (avatars). This will be vital to create mental health VEs that leverage the use of avatars for applications that require human-human interaction and communication. As Alessi et al.1 pointed out at the 8th Annual Medicine Meets Virtual Reality Conference (MMVR8), virtual humans have mainly appeared in MH applications to "serve the role of props, rather than humans." More believable avatars inhabiting VEs would open up possibilities for MH applications that address social interaction, communication, instruction, assessment, and rehabilitation issues. They could also serve to enhance realism that might in turn promote the experience of presence in VR. Additionally, it will soon be possible to use computer-generated avatars that serve to provide believable dynamic facial and bodily representations of individuals communicating from a distance in real time. This could support the delivery, in shared virtual environments, of more natural human interaction styles, similar to what is used in real life between people. These techniques could enhance communication and interaction by leveraging our natural sensing and perceiving capabilities and offer the potential to model human-computer-human interaction after human-human interaction. To enhance the authenticity of virtual human representations, advances in the rendering of facial and gestural behaviors that support implicit communication will be needed. In this regard, the current paper presents data from a study that compared human raters' judgments of emotional expression between actual video clips of facial expressions and identical expressions rendered on a
